Portable, preferably small bluetooth music controller for Android phone

Howdy army,

I've just bought an S3 and can't wait for the Pebble to come in 2013 (I didn't back it :( ), so I need something now that'll control music over bluetooth.

I don't need bells and whistles, seeing as I'll eventually get a Pebble, just a simple way to change tracks and pause. It's to replace an iPod nano for portable music while bike riding.

Does anyone here know of anything that'll fit the bill?
