That's exactly how the Tesla system works. You press the right thumbwheel on the steering wheel, (or the button above it on the S) and say "play rolling stones" or "play BBC World Service News" or whatever, and it just does. The left thumbwheel is the volume and you push it to the right to skip to the next song or station. The right thumbwheel changes the speed while on cruise control and I do sometimes mix them up and turn the volume up when I want to go faster or visa-versa.
