# ═══════════════════════════════════════════════════ DESCRIPTION ════════════════════════════════════════════════════
# This is a fun little project to create an album artwork display. It takes a track_info.db file with the track name,
#   album_name, and artist_name. It then needs to have an album cover in Album/<album_name>.png
#
# It displays on a 4:5 aspect ratio monitor vertically. It shows the album artwork with the track title, album title,
#   and artist name.
