"as i swing back/mood to mood/it's not because of you..."--MonicaWe all knew this was about PMS, even though some of us had never even gotten to PMS yet when this song came out. All my friends and I knew was that this little boy in the video was fine, the song jammed, and the video was tight. And the record still works, even at my advanced age. And even thought it's considered the "PMS" song, I reserve the right to swing back mood to mood for the rest of my natural life, pre-menstrual or not. One of the pleasures of being a woman, wouldn't you say?
