I've not found a game I CAN'T do this with. Indeed, I have to be reminded that the game HAS its own music; I turn it down the first time I run it, and then sometime later in the forums read someone mentioning the in-game music, and then realize it might be worth checking out. If you play a game for hours on end for several days, ANY included selection of music can get boring and repetitive, and I'm not one of those people who can listen to the same 15-second snippet of their favorite song 24/7/365. If I hear the same song twice in one day, I can't stand to hear it again for a month or more. Classical-style music, though, hasn't got as many notable sequences in it, so I can listen to a single CD several times without noticing. (The RRT2Platinum CD's music fits this description well enough too.)
