100 Greatest Underground Hip-Hop Songs of the Last 15 Years

Twitter again has its benefits. I follow Aesop Rock's twitter, and he recently posted this link:

I don't know who James Gunn is, but this list is incredible. Can't argue much with it, especially with so much Rhymesayers, Def Jux, and Quannum on the list. I don't see how Massline artists get no respect though. The best part though is that there are a bunch of artists and songs I've never heard on the list, so it's time to get downloading!
