Grinding Noise from back wheel

Just got my car and all of a sudden I hear a grinding noise from the back wheel. It sounds like a metallic grinding sound and follows my speed pattern.

Weird thing is the car drive and brakes fine. I had the music on and windows up and didn't hear it. When I turned the music off and out the windows down I heard it.

I looked at the tires and wheels and they look fine. I checked under the car (not on a lift though) and looked ok.

It's the strangest thing... Any ideas?

Could be one of a few things.
Rock stuck between heat shield and brake rotor (push heat shield back away from rotor a little bit to free it)
If it's a brand new 2018 and the dealership washed it, could be some surface rust on the rotor(s) grinding against the pads. Brake a few times and that should clear it up.
Could also be parking brake rubbing inside the rear hat, if it doesn't go away soon I'd take back to the dealer and ask them to check adjustment on the parking brake.

Thanks all. It was the heat shield touching the brake rotor. I pushed it back a bit and the sound is gone.
