Start Music in the same Tab...Facebook , without closing that!
Simply install the plugin in Chrome, and start discovering music. At its simplest, you can pull up a toolbar in which you can search for playable music to listen to while browsing (courtesy of Rdio and MP3s on blogs). Those songs can be shared with friends on Facebook via message, or they can be posted as a playable stream on your wall.
Enjoy music on facebook,, no need to open another tab!!
