but it could be something quite innocent and normal, like an embedded flash player in your homepage. Have a look at this page for an example (it's the official site for a movie, that plays background music by itself.) http://wwws.warnerbros.fr/ascannerdarkly/ (Interesting movie, by the way.)
Perhaps if you describe the music, and what you are doing on the computer when it plays, and does it play whenever the computer is turned on (all the time) or just when certain programs are open?
