THIS IS NOT AN EXTENSION CREATED BY NOR ENDORSED BY GOOGLE (Had to say that in big bold letters so the people who follow me hopingwishingdreaming that I give them their big "story" break don't run off breathlessly trying to out scoop one another about this and wind up making themselves looking not so bright in the process.)
That out of the way, I like this little extension for using Google Music. It pops up a little miniplayer so I don't have to keep the browser window open to control my music. Bangorang.
Since it can scrobble, I've resurrected my Last.fm account from the dust and ruins. If you wish to be Last.fm "friends" you may find me here: http://www.last.fm/user/EricaJoy
