When the game needs atmosphere and has a great soundtrack, there's no reason to turn it off. For example in Fallout 3. When I listened to all the radio songs, I just intalled some mods which included more songs, but in the same style. The same in GTA IV. I just added a bunch of songs to the game's folder.
But when the game has repetitive music and the atmosphere is not so important I make a playlist and listen to that instead. Those games can be games like The Pinball Arcade , Plant Vs Zombies or Hearthstone. Something that is not heavy on plot and characters.
I think that if the developers made sure to include an amazing soundtrack in accordance to the atmosphere of the game, there's no reason not to listen to it.
