Hey Mike, I have recently found out about this band, Theory Of A Deadman. It's actually pretty good. You would like it. I guess. Also, I have only just noticed that you didn't have Default, The Exies or Disciple on your list. You might want to check them out as well.
Fair To Midland get their album "Fables From A Mayfly: What I Tell You Three Times Is True". it's a solid beginning to end album
May or may not like but check out this band called Slot. It's a russian nu-metal band. A good addition to your list. They kinda remind me of Linkin Park except one of the vocalist is female. http://www.myspace.com/theslot
If you're a thrash metal person and loves Metallica to the highest. P.S. Check out TRIVIUM! They are so great, so talented, and so young! Hahaha
I asked Derek if I could bump this and he gave me the go-ahead. No sense in wasting space. Anyway, I checked out most of your suggestions, but as always, I'm looking for more. I think my list has almost doubled since I made this thread, so I'm going to post my revised list and then everyone else can throw what they think I should check out. 3 Doors Down 10 Years 12 Stones 30 Seconds to Mars 36 Crazyfists .38 Special Adema Alice in Chains Alien Ant Farm All That Remains The Apex Theory As I Lay Dying Atreyu Audioslave Avenged Sevenfold Beastie Boys Black Tide The Blank Theory Breaking Benjamin Bullet for My Valentine Calm The Cars Chevelle Coheed and Cambria Cold Crossfade D12 Damone Dark New Day A Day to Remember Def Leppard Deftones Depswa Disturbed Drist Drop Logic Dropping Daylight Drowning Pool Dry Cell The Eagles Earshot Electric Light Orchestra Eminem Enter Shikari Evanescence The Exies Faith No More Finger Eleven Fireflight Five Finger Death Punch Flyleaf Foo Fighters Fort Minor From Autumn to Ashes From First to Last Funeral for a Friend Garth Brooks Godsmack Gorillaz Grey Daze Guns n' Roses Hellyeah Hinder Hollywood Undead Hoobastank Hootie & the Blowfish Hybrid Theory Ill Niño Incubus InnerPartySystem Julien-K Killswitch Engage Kittie Korn Lacuna Coil Light This City Limp Bizkit Linkin Park Lupe Fiasco Lynyrd Skynyrd Marilyn Manson Mastodon Metallica Mudvayne Muse Nirvana No Doubt The Offspring Orgy Otep P.O.D.
