This is Korean rapper Vasco's 2007 hit song 덤벼라 세상아 (Attack the World) from his 2nd album with the same title. The music video of 덤벼라 세상아 looks like it is based on some futuristic Orwellian/apocalyptic Korean society. And in it Vasco plays some sort of hero that breaks the mold of conformity to the society's dimise.
