I meant off of itunes or whatever else people use. I don't use pay sites so i don't know. I make my own mp3s or download them. And the ones I download sometimes don't have id3 tags, or ones with different information. Zune doesn't like that. If you have the artist as Bun B and Bun B ft whoever it makes 2 different artists.
Ever try putting a Various Artists (mix) cd onto a Zune? If you don't change all the artists names to the same thing you have 17 different artists on your list. Ya that is exactly what I want when I want to listen to that full cd, listen to each song manually 1 at a time.
