it works! – A2DPblocker - Bluetooth Mono Review
great app (the only one as far as i could find) that enables you to play music through a bluetooth connection. designed specifically for use with your itunes library, but will also support other streaming apps such as iHeartRadio or PublicRadio - to do this, turn "remote control" off and play as normal through the playback queue, but turn the volume all the way down. this way when you switch to the other streaming app, it will play without the music running in the background. I asked the developer myself this same question and he responded in less than a day.
