Some mp3 files have tags encoded as ISO8859-1 but have russian text inside (cp1251). To fix this and encode as utf8 do

./fixID3tags -music-dir="<MUSIC>"

this will run in dry mode and show suggested changes. To apply changes, run

./fixID3tags -music-dir="<MUSIC>" -dry-run=false

Some mp3 files have incorrectly set encoding as ISO8859-1 but actual data is in UTF8, to fix this do

./fixID3tags -music-dir="<MUSIC>" -fix-ISO8859-1=true
