I'm sure this was discussed many many many moons ago. Cleaning out some of my old links from my favorties and came across this one.
http://www.moire.com/beastieboys/samples/index.php
Basically, the site is dedicated to breaking down every song off of the Beastie Boys 'Pauls Boutique" record and listing where every sample came from; the inside joke to almost every lyric; and what not..
I find it fascinating when looking at the magnitude of this project....Makes you appreciate the record even more......
