Muse

Muse is a Mac OS X music player for Pandora Radio that puts you in control. Use the media keys (F7, F8, F9), your own keyboard shortcuts, or the Apple remote to play, pause, skip, and rate your music.

Stream to AirPort, Apple TV, or any AirPlay-enabled device. Muse gets your music out of the browser and into its very own window-no more juggling extra browser tabs (or accidentally closing the wrong one). Plus Growl notifications and Last.fm integration-Muse makes your music better!
