A LOT of people have been freaking out about it being a possibly completely different song, actually. If everyone used their 'common sense', this little rework would have been expected. Similar to how country artists add layers to their songs for Pop radio. I don't understand why this was necessary, but Jive/RCA obviously don't trust Britney having a completely mid-tempo song. It is what it is, though.
I hear yah, man. And don't mind me, Rico.
I'm just still bitter about "Inside Out" being scrapped.
