I just updated my Galaxy S to 2.2. After that, once in a while, a track starts playing on it. I start killing all the applications on the phone one-by-one but no steady results. My wife just upgraded, like 2 hours ago, and as soon as she is done with some set-up--since all the settings on it has been wiped out--her phone starts playing the same thing too. This is not a song. This is like one of the intro songs to the games or softwares which are kind of neutral and repeat all over again, forever.
