I noticed that the background music takes a bit of time to load. Personally I'm not a fan of background music at all, but in your case it may be appropriate. If you insist on having it load automatically, you should address the loading issue, and place an off button somewhere noticable.
I also noticed that you have a large number of XHTML errors.
Yep, I'd agree. Definitely consider choosing a music player that doesn't have the auto-load feature... personally I hate going to a website and having music pop up out of seemingly no where!
