lyrico

lyrico is a command line application which downloads lyrics for your songs. When given a folder, lyrico will:

• scan it, and all inner folders, for audio files
• read the metadata for all songs that it detects
• download the lyrics for each song
• embed the lyrics downloaded into the song (as standard lyrics tag) and also save it to a text file

Current version of lyrico supports only unsynced lyrics.

Support

• Audio Formats - mp3, flac, m4a, mp4, wma, ogg/oga (Vorbis and FLAC).
• Python - Python 27 and Python 3 (tested on Python 3.5 Python 3.4)
• OS - Windows, Linux (tested on Ubuntu).

Installation

Use the standard pip install:

pip install lyrico

This will also install the dependencies. Hence, it is recommended to install lyrico on a separate virtual environment.

You can test if lyrico was installed correctly by running the 'lyrico' command, which now should be available:

lyrico

This would give the following output:

source_dir is not set. Please use the "set" command to set source_dir.
use "lyrico --help" to view commands.
Your current settings:

ACTIONS
    save_to_file = True
    save_to_tag = False
    overwrite = False


PATHS
    source_dir = None
    lyrics_dir = None


SOURCES
    lyric_wikia = True
    lyrics_n_music = True
    musix_match = True
    lyricsmode = True
    az_lyrics = False

If you get this screen, that means lyrico and its dependencies were installed correctly.

If you see an error like ImportError: No module named mutagen.id3, this means that the dependencies were not installed for some reason. In that case you can install them very easily with single command. Here's what you do:

1. Go to lyrico's GitHub page.

2. Download repository as ZIP and extract the requirements.txt file from it. It is in the root directory of repository. This is the only file you need.

3. Open command prompt in directory containing the requirements.txt and run following command (if you're using a virtual environment, activate it before running the command):

   pip install -r requirements.txt
   

   This will install all of the lyrico's dependencies and now you can try testing with the 'lyrico' command. It should give no errors.

Running lyrico

lyrico operates using two directories (folders):

• Source Directory (source_dir): This is the directory which lyrico scans for audio files. The scan also includes all the directories contained within.
• Lyrics Directory (lyrics_dir): This is where lyrico will save the lyrics' text files.

Before running lyrico you must set these using the set command. Values must be absolute paths to the directories. Once set, lyrico will remember your settings (which can be changed easily at any time). So this has to be done only for the first time.

This is how an example first-run would look like on Windows.

1. Set the source_dir:

   lyrico set source_dir D:\test\Music
   

   This logs the following message:

   source_dir updated.
   lyrico will scan the following folder for audio files:
       D:\test\Music
   

   When setting source_dir, the directory must exist beforehand. lyrico will not create the source_dir for you.

2. Set the lyrics_dir:

   lyrico set lyrics_dir D:\test\Lyrics
   

   This logs the following in command prompt:

   Directory does not exist. Creating new one.
   lyrics_dir updated.
   lyrico will save lyrics files in the following folder:
       D:\test\Lyrics
   

   Unlike source_dir, when setting the lyrics_dir to folder that does not exist (as in this example); lyrico will create it for you.

3. Run lyrico:

   lyrico
   

   This will start the application and it will start downloading the lyrics for songs that it detects in the source_dir. You will be able to see the status (song name, lyrics URL) in the command prompt as it downloads, one at a time, the lyrics for each song.

   Finally it builds the log of whole operation and saves it in the log.txt file. log.txt is located in your lyrics_dir.

Other Settings and Commands

Basic settings like source_dir and lyrics_dir can be repeatedly changed using the set command as described in the example above. There are few more settings that are available to control lyrico's actions. These actions can be either disabled or enabled.

• save_to_file - When enabled, lyrico will save the lyrics downloaded to a text file and put it in the lyrics_dir. The naming convention of file is as follows:

  [artist name] - [title].txt

  where [artist name] and [title] are extracted from the song's metadata. It either of this is not found, lyrics won't be downloaded and you will see that in the final log.txt. This naming convention in the current version cannot be changed.

  enabled by default

• save_to_tag - When enabled, lyrico will embed the lyrics downloaded into song tags. lyrico uses the standard lyrics tags for different formats. This means, as long as your music player can read standard lyrics tags from the song's metadata, it should display them.

  disabled by default

• overwrite - When enabled, lyrico will always download the lyrics for a song ignoring they might already be present in the lyrics tag or in the lyrics_dir as a text file. After the download, it overwrites any existing lyrics in the tag or the text file.

  This setting is meant to avoid repetitive download of lyrics. For example, if there is a song 'ABC' in the source_dir. And overwrite is disabled. When lyrico is run, it will first look into lyrics_dir if it already has lyrics. If yes, then it would ignore the song.

  overwrite takes into account, the save_to_file and save_to_tag settings to decide what to do. For save_to_file, it looks in lyrics_dir and for save_to_tag it searches for existing lyrics in songs's metadata. Whenever there is a void, download happens and old lyrics will be replaced by downloaded ones in both, text file and song metadata as per your settings.

  disabled by default

The above three settings can be changed using enable and disable commands. This is how you will enable save_to_tag from its default 'disabled' setting:

lyrico enable save_to_tag

This would log:

save_to_tag enabled
lyrico will embed the downloaded lyrics into song tags.

Similarly to disable save_to_file:

lyrico disable save_to_file

This gives following message in command prompt:

save_to_file disabled
lyrico will not save the downloaded lyrics to text files.

• Viewing current settings - To view current settings use the following command:

  lyrico --settings
  

• Help - You can always view all the commands by asking for the help screen:

  lyrico --help
  

• lyrico quick invocation - you can supply source_dir along with lyrico command. The following command:

  lyrico full_path_to_source_dir
  

  is same as running the two commands:

  lyrico set source_dir full_path_to_source_dir
  lyrico
  

  However this won't work for the very first run. When running lyrico for the first time after installation, the source_dir must be set explicitly using the set command.

Lyrics Sources

lyrico uses the following sources from where it downloads the lyrics:

1. Lyric Wikia : lyric_wikia
2. LYRICSnMUSIC : lyrics_n_music
3. musiXmatch : musix_match
4. LYRICSMODE : lyricsmode
5. AZLyrics : az_lyrics (disabled by default)

The search order is same as enumerated above and cannot be changed. You can, however, disable or enable any of the sources using the same enable and disable commands. When a source is disabled, it is simply skipped during the search.

For example, to enable AZLyrics:

lyrico enable az_lyrics

Use the command line name for the source, which is mentioned after the link to the source in the above list. This logs the following message indicating that az_lyrics will be used as a source:

az_lyrics enabled
lyrico will use AZLyrics as a source for lyrics.

Or to disable Lyric Wikia:

lyrico disable lyric_wikia:

This logs the following message:

lyric_wikia disabled
lyrico will not use Lyric Wikia as a source for lyrics.

Audio Formats and Tags

Below is the table of supported audio formats and their supported tags:

Audio Format	Tag
mp3	ID3 Tags
flac	Vorbis Comments
m4a, mp4	MP4 Tags (iTunes metadata)
wma	ASF
ogg, oga	Vorbis Comments

lyrico goodness

Here are somethings that lyrico does well:

• No junk - lyrico will not insert junk text into your lyrics files or audio tags. It won't create blank files or blank lyrics tags. Neither it would create lyrics files or tags containing errors etc.

• Language - Since lyrico uses your song's artist name and title to construct the URLs; so as long as they are correct and the source has the lyrics, it would work no matter which language.

• foobar2000 - The poor performance of the Lyric Show Panel 3 component was main reason I wrote this application. It simply won't work for me. lyrico plays nicely with 'Lyric Show Panel'. lyrico's file-naming convention matches 'Lyric Show Panel's default settings. Just point 'Lyric Show Panel' to your lyrics_dir and done.

  I recommend simply removing all of 'Lyric Show Panel' online sources and use offline mode (Tag search, Files search, Associations search) with lyrico. It is the next best thing to automatic search. Because 'Lyric Show Panel' on failure embeds errors in lyrics files and tags!

  Even if you don't use foobar2000 or your music player cannot read lyrics from text files like that, you can always embed lyrics into tags which should work with any decent music player including iTunes.

• log.txt - log.txt created at end of every lyrico run is nice way to see what have you fetched. It show list of every song present in source_dir along with status of download or errors that happened.

lyrico gotchas

Here are few points you should know before using lyrico:

• Your tags - lyrico uses metadata in your tags for building URLs. Hence your songs should be tagged with correct 'artist', 'title' information.

  lyrico also assumes that you're using standard tags for each format (container) of your songs. For example, lyrico assumes that your .mp3 files are using the standard ID3 tags and only reads metadata for those. If you are using something like an APEv2 tag with an .mp3 file, lyrico won't be able to read it and would log the pertinent error in the log.txt.

  You don't need to be concerned about this unless you have forcibly embedded non-standard tags in your songs with some other software. Table of supported tags for audio formats is given above.

• ID3 tag versions - lyrico will convert any old ID3 tag to ID3v2.4 if save_to_tag is enabled. This is the default behavior of mutagen; the underlying dependency used by lyrico to read ID3 tags.

  This has never caused any problem for me till date. And from my understanding you should be using ID3v2.4 tags anyways. I have used lyrico on hundreds of mp3 files and had no issues. You can always test lyrico on few songs and check. Or you can just disable save_to_tag.

• Song metadata - Lyrics are fetched using a URL generated using song's artist name and title. This means that if the song has titles like:

  • ABC(acoustic)
  • ABC(live version)

  or an artist like:

  • XYZ(feat. Blah)

  the download might fail. Sometimes artist-name or title contain characters like '?'. For this, Windows won't be able to create the text file as it is a restricted character. But the lyrics will be downloaded anyways and saved to tag if save_to_tag is enabled.

• windows console - If you are using Windows, like me, you must use some other font than the default 'raster fonts' in the command prompt to view in-prompt logging for songs using other characters than English in their metadata.

  But the problem does not end here. Even after enabling other allowed fonts like Consolas or Lucida Console, you still won't be able to see in-prompt logging (you will see question marks or boxes) for Asian languages like Mandarin, Japanese, Korean etc. Though European language are displayed correctly.

  Despite any issues with windows console display, lyrico downloads and saves the lyrics correctly to files and tags.

Dependencies

lyrico uses and thanks the following python packages:

• glob2: to allow simple recursive directory search in Python 27.
• requests: HTTP for Humans.
• mutagen: to read tags from audio files and embed lyrics in tags for multiple audio formats.
• beautifulsoup4: to extract the lyrics.
• win_unicode_console: because Python 27, Unicode and command prompt is a nightmare.
• docopt: to create beautiful command-line interfaces.

A note on mass downloading

Since lyrico is simply scraping lyrics off the HTML pages of the sources, please don't set source_dir to a folder having thousands of songs.

They might ban your bot. az_lyrics sometimes bans your IP (not sure if permanent) if you hit them with too many failed requests. Though, refreshing your IP by restarting your router or using a VPN solves that. Hence, az_lyrics as a source is disabled by default. Only use it if you are looking for recent lyrics.

Also, downloading 1000s of lyrics will be slow since lyrico does not batch-download. It sends one request to one source at a time. This is by design.

I personally use it at one or two albums at time and keep checking for any errors in log.txt.
