Even though Kanye West gets a lot of flak for his behavior, I think that most of the sampling that he's done (especially on his first 3 albums) has been amazing. Like taking a 2 second sound clip from Steely Dan's Kid Charlemagne and somehow transforming it into the main beat for his song in Champion: http://www.youtube.com/watch?v=4XaDeC2LEdA#t=68
Wow that was a great video. Big fan of Kanye's earlier stuff and some of the newer stuff, always appreciated the samples but great to see where they come from. Very varied. Everything from classical to Michael Jackson to Daft Punk.
