# Clean up a music library. Improved version of rename_music_files.sh.
|
|
|
|
# Steps:
|
|
# 0) Ensure an OLD folder exists, it is what will be refactored.
|
|
# 1) Convert all non-mp3 files to mp3 and put them in an INTERIM folder.
|
|
# 2) Loop over all OLD and INTERIM's mp3 files and move them to NEW based on data.
|
|
# - Name the file as "${ZERO_LED_TRACK_NUMBER}. ${SONG_TITLE}
|
|
# - Name parent folder as "${YEAR} - ${ALBUM}" if both exist, otherwise just one or the other "${YEAR}${ALBUM}".
|
|
# - Name grandparent folder as "${ARTIST} - ${GENRE}" if both exist, otherwise "${ARTIST}${GENRE}".
|
|
|
|
# TODO list:
|
|
# - Organize tracks by Artist + Album folders.
|
|
# - Name parent folder as "$YEAR - $ALBUM" if both exist, otherwise just one or the other.
|
|
# - Name grandparent folder as ARTIST if it exists, otherwise GENRE.
