It happens to all of us — we get a song stuck in our head, for better or for worse.  I woke up yesterday with "Alone" by Heart in my head (perfect for belting in the shower, for the record).  As the day progressed, I was influenced by a link that my friend Frank had in his GChat status to this, which featured a cover of Hall & Oates' "One on One" as the song of the week.  Boom — stuck.  This morning's song, prompted by nothing I can pinpoint, is "Love is Pain" by Joan Jett.  Actually, maybe it was reading the interview with her in last week's Time Out over dinner last night . . .
