Some albums that I think are really good (your musical tastes may vary, of course):

• Diablo Swing Orchestra
• Kangaroo Musique
• pornophonique

Yeah, the major features that I want to add that aren't in there yet are tags search and playlist creation. Other than that, it's certainly comparable to the official jamendo.com iphone app in terms of features right now (and they don't support tags search either..).

I have

• featured playlists
• radio support (only the top 20 radios right now)
• search for artist/album/track
• download support / kind of.. right now it opens a .torrent link in the browser. I intend to detect if you have transmission installed and send the link there directly.

Especially the radio support is, in my own humble opinion, way better than that in the iphone app
