Musicality - Last.fm, Grooveshark and more! 1.3

Musicality lets you switch quickly and easily between Pandora, Last.fm and Grooveshark (with more on the way) so you can enjoy your music no matter where it lives.

Get your music out of the browser and into a streamlined window of its own. Close it, and the music keeps on playing. No more juggling browser tabs, or accidentally closing the wrong window.
Use the media keys or define your own keyboard shortcuts to play, pause, skip, and rate your music without leaving your current application or even taking your hands off the keyboard.
