Itunes gift cards and buying music?

I tunes doesn't use the format .mp3 for songs. they use their own .m4p, protected content format. You can buy songs that are drm free off of itunes, those are called itunes Plus songs. Look for them. Not every song comes in protected and unprotected format and the drm free songs cost a little more. If you wish to get your protected songs into a mp3 format, then burn some songs onto a cd using itunes. It has to be an audio cd( format that you can play on cd players) then re import it to the zune library on your computer.
