Best Collaborations

What are some of the best collaborations in songs?

I would say mine are:

Pearl Jam and Soundgarden= Temple of the Dog

Corey Taylor(Slipknot) and the band members of snot= Requiem

Sevendust and Snot= Angels Son

Mark McGrath(Sugar Ray) and Snot= Reaching Out

and every song off of Strait Up

Coal Chamber and Ozzy Osbourne= Shock the Monkey

Limp Bizkit and Aaron Lewis(Staind)= No Sex

and a lot more i can't think of

BB King and Eric Clapton... Bryan Adams and Bonnie Raitt are my favs that I can think or right now.

Aerosmith - Kid Rock - Run DMC - "Walk this way"
Played at some awards. I hate rap but I love the way the two types of music work together.

Also "Aint No Nice Guy" by Ozzy, Lemmy n Slash
Great Blend of Unique sounds, I knew it was Slash soloing on the song! That tone and use of the pentatonic scale!! Awesome

the best collabs in my opinion were:

1. Deftones with Max Cavalera: Head Up

2.Max Cavalera with Chino and Grady: Pain

3.Seplutura with Jon Davis from Korn: Rattamahatta

4. that one song that S.O.A.D did with Wu-Tang

5. Down (since that whole band is basically a big collaboration.)

and thats pretty much it since most collaborations suck balls.

Gary Moore w/ Phil Lynnott - Parisienne Walkways & Out In The Fields

Lenny Kravitz w/ Slash - Always On The Run

Michael Jackson w/ Slash - Give In To Me

Santana w/ Matchbox 20 - Smooth

Santana w/ Everlast - Put Your Lights On

Bob Dylan & George Harrison - Yesterday (Yes the Beatles one, its cool more Dylansey than the Beatles version)
