And an fascinating study of Girl Talk too. What is Girl Talk? Well, it is the stage name of Gregg Michael Gillis, who is a master of the mashup. An d what I like about this site is you can follow along and see just how many sources he uses to make each track. It’s incredible for me. Mashing up Jimmy Smith, Cream and Notorious B.I.G. is just one of the eclectic mixes you’ll find here.
I should highly add that alot of the lyrics are NSFW. Alot! I recommend earphones.
Smart People I Know 
Not my taste in music, but still….neat!
Very innovative mixes here. ; )
It IS innovative. I don’t love it unconditionally, but I am impressed by the ability to create something so seemless from all those parts.
