OK here's one at the opposite end of the price scale...

For SqueezeBox users, it's worth having an android phone for this software alone, it is much better than using the 'Controller' (functionality, response time etc.), and at £2.50 or so for the application it is somewhat cheaper.

I run it on a Desire, my missus runs hers on a Hero, we can happily control 3 players in parallel, with large playlists, without the performance issues that the controller introduces at these 'stress' levels.

N.B. I have no vested interest in this product, other than as a user
