I have a ~2121 MP3 collection, each one of the carefully tagged before it is added to my MP3 library folder.
MP3tag is the best tool to do so, but today I decided to check if everything is ok with my tags and opened my library in MP3tag, and something odd is happening:
Many (I woud say 50 out of 2121) MP3 don't show any tags, but in my player (winamp) those same MP3 appear to have tags, for example the one selected in the previous screenshot is Ace Frehley - New York Groove, and look how that MP3 shows on Winamp:
what could be happening?
