I love this

Finding the sources of samples in songs has always been a rewarding hobby. Apart from being just plain fascinating, Ive found tons of great classic music this way. I have a list Ive been working on for a few years, but this is far more comprehensive than what Ive got. Good interface, and a really cool way to explore the genealogy of music.
