and thats about it...

not in any real order.... Classic(Eric Clapton), Southern(Lynard Skynard), Numetal(Nickleback), Psycedelic(Pink Floyd), Pop Rock(Linkin Park), Punk(The Unseen), Metal(Black Label Society), Hardcore(Norma Jean), Deathmetal(Six Feet Under), Mainstream(My Chemical Romance), Hair(Poison), Power Ballet(Meat Loaf), Screamo(Hawthorne Heights), Emo(Oneline Overdrawing), Goth(HIM), Industrial(Rammstien) and then you have mixes of these... But that is most I can think of.

man...there are hundreds, two bands can have very little difference yet be classified as different genre's.
Metal all the way!

I was going to just type all of the ones I knew... and I actually started...

But this is a more effective way.
