NEVER put sound on a website by force. If a user wants to enable sounds, then that's fine. And if you do decide to put a music file on there, and you have it in a 10 second loop, PLEASE have a way to disable the sounds.
Site Owners and Designers often forget that the majority of people who are visiting a site are not doing it from their home, but doing it from their work/office computers. As such, having sounds come out of a work computer will usually result in leaving the website.
Personally, I've never had a sound on any of my websites (nearly 15 years now), and I've never had a complaint from a user ASKING for music/sound to be displayed when they go to a site
