I was talking to Jessica yesterday about the differences between the music sites.  Beatport.com lets you listen to a sample of songs, like last.fm does when you wander into the store portion.  But the web 2.0 cred like this Yahoo Pipes page using it and Youtube, social (music) bookmarking features on last.fm, html instead of Flash (for stuff like permalinks), and radio-style format which plays full songs for free make the site a real competitive threat to more conventional retail operations like Amazon, Beatport and iTunes.
