Last.fm is amazing! The whole update is fantastic. I mean an update where there was actually thing's updated and added is so strange it just might work.
Twitter, Facebook, Last.fm, news feed's and a lot more stuff.
The free satellite radio is probably the coolest feature, lots of music stations to listen to, Their is a Pink Floyd, Metallica, Beatles etc... then it compiles a list of music you might like etc... It even streams MP3's and read's those labels.
Cant wait for the full on Update next month.
