Favourite artist?

I need to add more music to my collection, so I figured I'd ask people what their favourites are.

What's your favourite artist, what do you think is their best song and what is your reason?

 

T.I. - U don't know me, I'm back, Ain't I, Shoulder lean, Whats up whats happenin, bankhead, etc..
Eminem - Almost famous, Till I collapse, love the way you lie, W.T.P, Etc..
Metallica - Fade to black, One, Ride the lightening, Enter Sandman, Nothing else matters, king nothing etc...
Godsmack - Cryin like a bitch, voodoo, I stand alone.

Too many to count.

 

Metallica - One, All nightmare long, astronomy
Disturbed - another way to die, down with the sickness

 

Red hot chili peppers- Readymade, Don't forget me, (complete live at hyde park album)
Gun's N' Roses- Chinese Democracy, all their greatest hits

 

Wow. This is kind of hard. I have 2 favorite artist.

Slayer - Raining Blood - brutal riffs, hardcore solo that makes you want to mosh
Iron Maiden - Phantom of the Opera - insanely fast riffs, harmony of the solos blows you away

 

LMF - Rap Core (Rap and Rock and maybe some other style at the same time).

Beyond - Cantorock, Cantopop, et cetera.

-LeetNeo.

 

Eluveitie - Tegernakô
