I love this application and am more than willing to pay the $3/month for it. They updated it, and man, I love the new interface.
Yet to be determined - did they add Bluetooth headphone as an output. My bluetooth is charging s it was dead when I got this update, so I will have to wait a few minutes to an hour to check.
(Now I'm just waiting for Sling Mobile for Android... man! July cannot come soon enough!)
