This Super Mario World beat is absolutely untouchable. The slick rhymes of JimmyTheLoch add plenty as well. 

Much like SMW is in my untouchably perfect games list, this beat sits right alongside it. If I could hear a variety of rappers on one track, it would be this one. I would kill for a loopable instrumental. I'd beat all of Super Mario World to this, nodding my head the whole time.
