That's my point, I don't want to have to 'mess around with it', I want to be able to touch and go so that it's no more difficult than changing the station on my radio.

If you still don't think it's safe after that, I recommend you cover every control on your dashboard besides the steering wheel and the ignition switch with duct tape.

Or better yet, get a bus pass.

This is just what I'm looking for too, with one simple modification; Simply make the last played stream rise to the top of the pile. That would automatically make the stream list also a history feature, letting me easily switch between my most favorite stations while driving at 70 miles an hour (right now finding the right stream is potentially fatal)
