Good new everyone! Last.fm, everyone's favorite radio scrobble service has finally gone to Mango with version 3.x. You can now minimize this bad boy in the background and enjoy your radio with multitasking Mango goodness. In addition, you can pin your favorite radio stations to the Start screen for easy and quick access.
We've only played with it for a little bit but darn it all, it's a nice app--fast, smooth and great work on the integrating "Sharing" option. And considering this service is built into the Xbox 360 (for Gold Members), this a great extension to your phone. Grab the free app here in the Marketplace.
Thanks, Lerimer S., for the heads up!
