When you purchase music from iTunes Store, you actually get DRM protected content (in protected AAC or M4P format), which you will not be able to play on MP3/MP4 players and other non-Apple mobile players. You cannot directly transfer the M4P files to Zune, PSP, BlackBerry and Android phone, either. In such case, the option is to burn those tracks to an audio CD and then rip them once again to your computer hard drive wherein the DRM will be removed and you will get the tracks in (DRM free) MP3 format. After this you will be able to transfer them to Zune, PSP, BlackBerry and Android phone.
