ive exeeded the maximum amount of names so epicaly that ill stop

slash is a guitarrist

Dickinson is no way the best vocalist, Paul di' Anno was much better than him

Actually, I don't think that any Maiden vocalist was good enough to be in the top 5.

But for sure, Steve Harris (bass), maybe Niko McBrain (drums) and Dave Murray (Guitar) also.

btw wth? Only gods3nd mentioned David Gilmour? >.<

Guitarist:
Alexi Laiho from Children of Bodom
Vocalist:
Marcus Bishoff from Heaven Shall Burn
<----

Also there should be best Keyboard and the best is:
Janne Wirman from Children of Bodom

drummer - cozy powell
guitarist - none xD

Dude.... you have no idea. Do you actually know what a bass is?

Slash - Lead guitar in Guns N Roses and Velvet Revolver
Kirk Hammet - Lead guitar in Metallica
Robert Trujillo - BASS, well done
Steve Harris - BASS, gratz again, IRON MAIDEN
Nicko McBrain, Drums, IRON MAIDEN

On a side note, lol at your inclusion of Mike Wengren and David Draman. Disturbed are the most talentless band around since Greenday.

on the contrary dude i like "wake me up when september ends"

gay song >_>
