DRM: Pay More, Get Less
Digital Rights Management, or DRM, is the software that makes it so music you buy from the iTunes Music Store can't play on any other player other than the iPod, such as a Zune or Sansa. In an effort to keep people from sharing legally purchased music, DRM actually goes much farther than copyright law dictates, denying paying customers the fair use of the music they buy. You should be able to do what you want with an album once you've paid for it; like a CD or a record, you now own it for life.
However, music wrapped in DRM software cannot be played on devices other than those explicitly tied to the store you brought it from. Furthermore, listening to your music across multiple computers, or moving your music to a new computer when you upgrade, is often a huge headache that ends with you needing to repurchase your songs.
This is not true obviously these guys obviously never knew that if you burn a CD with the purchased songs off iTunes you can rip them back to your computer DRM free! :D but i'm soo gonna follow this through to the end.. hello www.isohunt.com
