I've listened to a few mashups...

seems like everyone with a laptop and Reaper have tried their hands at it. There's a lot of bad mashups out there honestly.

5 & A Dime is pretty good though - look up "Hide ya Kids Hide ya Dubstep"

Kap Slap is awesome: "Illmerican Blow," "Better Than a Stereo Dream," "Dubmau5" are some good ones.

Anybody else know some good mashup artists?

Every time I try to pick it up like falling sand,
As fast as I pick it up,
it runs away through my clutching hands.
There's nothing else I can really do...
