HTX 8x and Metro Radio Pro

[lzicc]

I thought this was odd. When I start up my car, Metro Radio starts playing over my car stereo via Bluetooth. If I hold down the arrow key on the phone to find the app it so I can stop it from playing, it doesn't show that it is open. If I go to open Metro Radio, the music stops while it is opening almost like it was never open in the first place, then starts playing. I wonder if it is the Metro app issue or the phone itself.
