Bluetooth music feed skipping?

I have a Belkin NFC-enabled HD Bluetooth Music Receiver connected to my stereo. The device is paired with my MacBook Pro. When I'm perusing the internet or downloading something while listening to iTunes, the music begins skipping and hanging. Sometimes, I get a Bluetooth error saying the selected device cannot be used and the music continues playing through my laptop speakers.

Why does this happen? I would assume the Bluetooth connection and the internet connection would be mutually exclusive. Is there a way to fix it?
