haha i have been listening to both of these albums for years, and just now realized they share a title among them. both good songs... although i think the one on "dance floor" is more musically interesting.
There is no excuse for 2 songs by the same artist with the same title. NONE.  Both songs are great, Bedtime song is more sexy and nostalgic, Confessions song is more dancing, but both are amazing <3
