I know the thread is "AirPlay" but I think it would be foolish to leave out Android with GooglePlay users.

The "Q" is pretty innovative in that it allows people to create play lists and "send it" to Q automatically. It's a different way of thinking about how music can be created in a large party. but I digress.

It would be great if Android support is embedded as well.
