Website music

I’ve done some searching on the internet, and haven’t found anything yet. Thought I’d post something here aswell.

I’m creating a website in flash, and I want to have some sort of background music on my site. Where visitors can control the volume and mute the music. Maybe also switch to another song.
Simple! As seen on many sites.
But my problem is, I don’t know how to do this!?

If anyone’s got a nice tutorial and or would help me otherwise, I would be very thankfull:)
