hoping someone can help, here's my problems

i have site with 2 columns

top.html (has a bunch of links
center.html

now when a linked is clicked the background music will still play. I put the code for the background music in center.html and for example if i click a link from the top of the page it will target to the center column but still play the music. I just want the music to play on the opening page. Any ideas what i'm doing wrong...(but you guys understand what i'm trying to say :P )
