Is there any kind of music playing in the rooms while you are trying to escape

Yes, there is music playing during BOMBSQUAD, which is dynamic depending on which part of the game you’re in. In Curse of the Mummy there is ambient sound, just like an Egyptian tomb would be.

No music. Ambient sound in the Egyptian one and the tv in the bombsquad

I dont remember any but you really have to talk with your team to get through the rooms so I'm not sure if you would want the music playing
