don't all free webservers support background music??
all you need is the html code and it should work
i usually just used freewebs.com cause it's easy to use.....but if you're going to have a big site then i don't think freewebs it is good cause it only allows a maximum of 50 pages
there's also one called atspace but i've never tried it before so i don't know....from what i've heard it's good
