For tagging file outside of EP (I use kid3), are both ID3v2.3.0 or ID3v2.4.0 versions compatible? I did a fair amount of searching for the answer with no luck. Also is there documentation (either from Denon or users of EP) mapping EP fields to corresponding fields in Serato, Traktor, Rekordbox, etc? ( don’t mean approximations, but the actual field to field mapping.) Thanks!
