I know, Michael Jackson just died and it's normal for one of his songs to be playing on a loop in one's head. But why this song? I don't think I've heard the entire song!
Cover of Off the Wall
Oh, well. I'd just go buy Off The Wall from iTunes. And I'd upgrade to the iTunes Plus version of "Butterflies" (from the Invincible album), which I forgot to transfer from my old iPod to my iPod Touch.
By the way, LSS means "last song syndrome" - as in, the last song you hear keeps playing in your head - for those who didn't know.
