Girl Talk is the #1 most over rated "artist" in Electronic music.
He takes quality old school songs and mashes them with extremely under produced beats that sound like an 8 year old made them while waiting for his next flight at an airport.
I have absolutely no respect for him.
If you want a real mashup artist Z-Trip is as good as it gets. His sound is way more mature, and none of his tracks sound flat and under produced.
