One thing to keep in mind with things like embedded music and some of the other bells and whistles. At first it may seem like a neat little feature to have or it may add a feel or ambiance to the site you have to imagine what the website is going to be like on the 10th, 50th, 100th, visit for a particular user. Things like music are often better left off by default, and allow the visitor to turn it on if he/she wants.
Good luck with the website.
