I'm kinda mixed on this. The selection of music channels is fantastic, with a lot of high quality stuff - but the bitrate seems to vary every few months. At first I got 128kbps on everything, then 16kbps, now they're at 64kbps.. it's a bit weird.

The app itself is tidy and fairly nice UI-wise, especially for a major corporation. The login feature is broken and never remembers my password, though, and overall I just wouldn't mind if there was some method of adding the stations as standard Shoutcast (or whatever) streams to iTunes.
