I'm looking into this (again! I used to buy from 7digital but it seems they're no longer in the same business model) after having used Rdio for quite some time, because I just hate not being able to play songs when I most want to because I don't have internet or it's flaky or I'm at another machine. From a quick research it seemed that Amazon MP3 was DRM-free.. not that I trust them too much or would want to support Amazon, but it seemed the only option with a good catalogue.
