I couldnt really find a specific place to put this so i put it here because it could incorporate some server side aspects

I want to incorporate a music system across my site.
A radio style system, where the music/radio/or whatever sound i choose plays consistantly regardless of what the person is doing. With no stop starting when they navigate through my site.

Im just wondering is their a simple way to do this. I have seen hacks for open source forums such as phpbb where you can add a radio feature to them.
Something similar would be ideal here.

im sort of stumped myself, but ive probally missed an obvious one.
or is it even do-able

Thanks in advance
