There are a lot of tags that I don't want in my music that beets seems to sync by default. For example, on one of the songs in my library, there is ALBUM ARTIST, ALBUMARTIST, ALBUMARTIST_CREDIT, ALBUMARTISTSORT, ARTIST, ARTIST_CREDIT, and ARTISTSORT. These are all the exact same value. All I need is one tag for album artist and one tag for artist. There are also many tags that exist but are empty, such as ARRANGER and ENCODER.
I also like my track numbers to be padded with zeros (01, 02, 03, etc), but it appears that by default, beets does (1`, 2\2, etc). Is there any way to change this?
