Another thing to bear in mind about Royalty Free sounds (and images for that matter). You are granted free use (hence the Royalty Free tag) via licence, but that use is usually limited to personal projects with no wider audience than your immedaite family and friends. Placing a sound file on your web page is deemed as broadcasting, which most would see as a breach of the terms of use of the sound file.
Just out of innerest, did you have a perticular piece of music you wanted to use?
TFC Nothing is a problem for me...
