-# This script will:
-# - find unimported music in $IMPORT_DIR
-# - use metaflac to add replay gain to all files
-# - (optional w/ --musicbrainz) use MusicBrainz data to tag the files
-# - match the artist with a known list of romanized japanese artists, and
-# 	replace the artist tag with the native japanese artist name
-# 	note: the album will still be placed under the romanized name folder
-# - copy (or move with --move) the music to $MUSIC_DIR/Artist/Album
