Its a guy singing slowly but not too slow

its not an old song, probably dance or pop or something. All i remember is, something like dada da, da, da, dahh OR is it bada da, da, da, dahh OR is it dada do, do, do, doo OR something like that. All i know is it ends with, "a" I thought it was jay sean or jason derulo or chris brown or someone like that but its not. So it sounds like them.
