I actually don't know, LOL. I like the song, but I thought it was a bit of a rip off (the first time I heard it before they said it on the radio I said to myself "that sounds like Holiday!" but I read somewhere that the guy that worked on the album with JS for this song IS the same guy that did Holiday for Madonna, so that is why. AND, I thought I didn't like the song, but everytime I hear it I sing along and dance in the car. And just reading the title of this post got it stuck in my head! It is just one of those songs that gets stuck like that *snaps fingers*. LOL. So, it has kind of grown on me
