How dumb court decisions made it impossible to sample like the Beastie Boys

Damn, this author really doesn't listen to a lot of music. Greg Gillis has become the poster child for mashups, but mashups had been a part of the cultural zeitgeist for a long time before Girl Talk was discovered.

Just one famous example: http://en.wikipedia.org/wiki/The_Grey_Album

This is to say nothing of all the heavy sampling in EDM in the last decade plus.
