DRM or digital rights management can save you a dollar every time you download a song. At least this seems to be the case as Yahoo! and Sony are offering music downloads that are DRM free but are charging $1.99 per song instead of the standard iTunes price of $.99. I think DRM is a great concept but inhibits use of content to some extent. The reason is that every user is different and some want to listen to music in multiple places on multiple devices and DRM is not as flexible as it could be.

So DRM keeps people from truly maximizing their use of the music and other content they pay for.
