I have a Coby MP620-8G mp3 player. For some reason, I've been getting a whole bunch (at least 15 albums) of my artists thrown into the Unknown Artist category, making it difficult to find songs. In my itunes library, they are all correctly labelled- artist, album, genre, etc. And when I open up the mp3 player on my computer, there isn't even a file called 'Unknown Artist', all the songs are in their correct folder with the correct label. But once I turn on the mp3 player, suddenly all those artist folders are gone and the songs are buried in the Unknown Artist folder. (It also seems to have thrown the track numbers in front of only those songs- thus when displaying all songs, it shows all teh first tracks of those particular albums and then the second tracks, rather than organize it alphabetically- the unaffected albums are listed alphabetically after the track number line.) I have noticed this problem has only occured with albums that I own the physical copy, but not all of them. Any song that I got from another source remains correctly labelled. (Although a couple bands randomly end up in genre '17' or '50'- also not in existence in my itunes library.) Anybody no what's going on here?
