I am having some problems with organizing my music. When I have the device mounted to the comp, I have all mp3 files organized by artist and album, and all named appropriately. When I go to play the files on the phone, a few artists and albums are organized in the "unknown artist" folder, and I can't fix the problem. Using the moment file viewer, I can see all the artists properly titled and organized, but the music player won't name them correctly.
