The chorus of B.o.B.'s Nothin' on You ft. Bruno Mars feels totally similar to the style chords used by Gorillaz, specifically ones in the chorus of their song Dare. I remember this hit me when I first heard Nothin on the radio, and I looked at the Gorillaz songs I have listened to, and Dare fits the bill best. The place I see the strongest similarity is at 3:02-3:06 in Dare, and 1:06-1:14 in Nothin'.

Maybe it's just me...
