Long term this is probably one of the next companies that will lose big when Apple rolls over its turf. Apple does music better (much better) than anyone. What happens when they integrate [Siri voice command] into the steering wheel and give cult users direct access to their docked iphone via voice, which will include the Pandora service? One of those things is they will no longer need to pay monthly for a music service from [Sirius XM].
