By the way, YouTube identifies it as "ogm_1991" by "OGM:unknown artist". After some research I found out that OGM stand for Old Georg Music. Haven't found the song title though but I put that info for you to help out.
Info from wikipedia:
"Perfect (Exceeder)" is a collaboration between Dutch musician Mason and American rapper Princess Superstar. The track is a mashup of Mason's 2006. instrumental dance track "Exceeder" and Princess Superstar's 2005. single "Perfect"."
