Soundbar and Bluetooth radio question.

I'm trying to piece together the last part of my little media hub. Nothing fancy but I have a nice soundbar with sub and I want to listen to music from it. More specifically, radio. It is Bluetooth capable. SO, my question is, what would be my best option for accomplishing my goal? I envision a small radio on the lower shelf that my kids could use to listen to music but I'm not sure which direction to take for this simple piece of the puzzle. Thank you in advance for your help.
