Amazon.com recently released an online digital music store that sells mp3 files without DRM. As far as I know, this is one of the first of its kind (eMusic did something similar, but they are subscription based and also had mostly indie music). This store has a lot of mainstream music and the prices on much of the music are better than the iTunes Music Store’s DRM’d music, and a lot cheaper than the DRM-free music at iTMS.
This is exactly what the digital music world has needed. The songs will play on any portable music player that supports mp3 (which I think is everything). If you were thinking about buying a song from iTMS, I would strongly recommend checking out Amazon’s store first. If they have it, buy from them. Support lower priced DRM-free music on a (somewhat) standard file format (at least a whole lot more standardized than AAC).
