Alright, didn't know where to post this. I have a collection of MP3's. I have changed over the years from using Itunes to WMP. I have noticed now, that some of my albums only work (able to add to library) in WMP, and some only in Itunes. Is there a program, or away to make sure all my music works in both players and is organized the same? As in keeps all data, and cover art etc.
