I really like the games that have no music except for certain targeted occasions. For example, when entering battle, or to emphasis a particularly tragic or particularly joyous scene.
If the music is on all the time, I'll put it down to either 0% or where it's just barely audible. I'll unfortunately miss some good music because of this, but I avoid the annoyance of music on all the time, much of which I don't like. Soundtracks let me enjoy the good music in a game if a friend tells me about it.
Regards,
