It also suits the romantic optimism of the song. Co-written by Alicia Keys, 'Million Dollar Bill' is a midtempo disco tune with a message as feelgood as a Nora Ephron movie. "If he makes you feel like a million dollar bill," Houston sings on the chorus, "Say oh-oh-oh-oh". This isn't the most exciting thing she's ever recorded, but it is classy, dignified and pretty timeless-sounding. Isn't that just what you'd want from Whitney in 2009?
