I recently upgraded by old Wildfire to a Galaxy S2. For an event I'm running, I'd like to be able to hook the wildfire up to a sound system and play music (that's on the wildfire). However, I'd also like to control the playback using my S2. This can be via bluetooth or wi-fi, as I can use the wi-fi hotspot feature if required.

Can anyone suggest any Apps that would allow me to do this? So far a remote-desktop app is the best I've found, but it's a bit awkward to use.
