Whats the name of that song ?

that was on mtv...i saw it on mtv about 6 weeks ago i think...its a black guy singing and the video is in black and white ink and it sounds like hes saying the word crazy..thats the only part i could remeber, its a very distinct music video and its not like there is alot of ones that look anything like it. I think its obviously r&b or hip hop or rap or one of those..please help me with my partial amnesia (lol) remember its a music video with the word crazy in it somewhere and its in black and white ink looking type thing
