if you were 5 hours into what is becoming a great story, you would prolly keep playing. I don't know anyone that stopped playing a game they were enjoying immensly because of some music they didn't like. They would just turn it off.
I suppose offering a choice is out of the question? ;)
You are standing in a village in 8000 BCE. Would you like the villagers to play:
1) African/Balinese gamelan music
2) Spice Girls' "Wannabe"
3) Toby Keith's "Courtesy Of The Red, White, And Blue (The Angry American)"
Your choice?
