pandora is that great music streaming thingie-a-ma-do-dad. but rather than just listen to it in a browser, you can use this new app called pandoraboy:
this uses (i assume) the embedded osx webkit engine to load the flash plugin to play the music but then it adds two bits of coolness on top:
so it will tell you, via growl what's playing and you can skip, pause etc via user defined hotkeys. and it's available at the low, low price of free. cool, eh?
