how to pause sound?

[Silverthorn]

but what about the other problem tho. how do i stop it from playing?

Considering that the game is designed in a matter that sounds will always play to their full length, the only solution to that would be to break up the splitted music into much smaller parts and let the music-object loop through them. That way, it stops pretty soon after quitting (depending on the size of the chucked parts, this might be shorter or longer). The downside of it is, though, that, as soon as you start playing with a lag, you will have an extremely ugly background music as it will pause between each file until the timer is used up.
