If navigating away from a musician’s timeline on Facebook to get a quick listen isn’t your favorite activity, you’re in luck. The folks in Palo Alto dropped a “Listen” button on artist pages today, giving you access to popular tracks instantly. Situated right beside the ever important “Like” button, the new feature first asks if you’d like to open your favorite music-streaming app — either Spotify, MOG, Slacker Radio or Rdio. If you’ve yet to link a service to FB, it’ll ask which you’d prefer to use. Once prompted in Spotify, for example, the app heads to the band’s library and begins playing selections from the Top Hits category. The “Listen” button then becomes a play / pause control and clicking one on another artist’s page makes the change in the app in a flash. To grab a look at the new control in action, head to your band of choice to give it a try.
