About Apple's DRM

I stumble upon this, which might clarified the question raised yesterday on the new DRM-free itune's song:

Does the lack of DRM mean that it’s okay to give copies of the songs I buy to my friends?

No, copyright law is still in effect—passing songs around is music piracy. However, the lack of DRM allows you as the consumer to be the judge of what’s right and what’s wrong, giving you a flexibility that DRM couldn’t. For example, imagine parents and kids co-mingling their music libraries. That seems absolutely fair to us, although in many cases quite unlikely. And if you opt to share your iTunes library on your local network, others can stream the songs you’ve purchased from the iTunes Store (currently people can see them, but if they double-click on a song to play it, they’re prompted to authorize their computers to be able to listen). But putting a song up on a file-sharing service and letting 20 of your friends download it? That’s now possible, but not exactly ethical. (And it’s fair to note that iTunes does embed your iTunes ID in every iTunes plus file you download, so it’s easy to see who bought the file originally.)

It is effectively easier to share song, but your name is tagged to the file so you cannot upload the song with impunity. You can check out the whole FAQ on

On another note, I guess Apple remove the DRM because it was hard/impossible for legitimates customers to use their file the way they want while users of pirated version could use their material without restriction. In my opinion, DRM was encouraging piracy rather than hinder it. Buying music felt like a real rip off (it may still does though...)
