B.o.B f/ Bruno Mars "Nothin' on You" (2010)
Weeks At No. 1: 2
Producer: The Smeezingtons
Not to discredit B.o.B., who found mainstream success after making his name in the Atlanta underground for several years, but this song was all about Bruno Mars. His songwriting team the Smeezingtons did excellent work; with a chorus that goes, "Beautiful girls all over the world/I could be chasing/but my time would be wasted/they've got nothing on you" coming from someone with Bruno Mars' face and voice, who could turn down such a compliment? The answer was no one, as radio stations across the country kept the song alive that summer.
