I have a colab between Wu tang and System Of A Down. While these are both great bands when they're apart this song totally sucks.

Basically, it's the singer from SOAD trying to rap without realizing that a lot of rapping is in the pronounciation. So he stumbles through it, and the worst part is when he does ODB's part, only he "Get's Fuzzy Funky For Ya".
Anyway, ya gotta hear it to appreciate how truly fucking awful it really is.
I got much love for The Clan, I love the fact that they'll do a colab like this, but in this case, it's garbage.
Stick With Rage Against The Machine!
Oh, and absolutely no Linkin Park colabs, I mean it, nottafinga!
