Amie Street, the music store that sells songs on a sliding price scale based on how popular they are, has launched a totally revamped website and new features including a new music player and an enhanced recommendation system. We’ve been big fans since first hearing about them in 2006.

Despite Amie Street’s growing popularity, especially in the indie music scene, the site has long had a somewhat barebones or even amateurish look that was functional but not very visually appealing. The new site is much more professional, with a rotating ‘featured’ panel prominently displaying new releases and promotions, and more intuitive overall design.

New features for the release include a new music library/player that looks very similar to iTunes. Users can access all music that they’ve purchased through Amie Street and stream it from this player free of charge, from any computer. Users can also browse through the music libraries of their peers, though they’ll only be able to listen to brief previews of songs they don’t own (the company hopes to eventually include full song previews, but it sounds like this is still a ways off).
