Usually I just find something else to listen to, I out grew "metal" when I turned 14.
If it's your bag, then enjoy it. Banging my head against door frames , to me , is a pointless pursuit. As much as I have tried, I have not found much to like in "new" music sense 1985. Monotone, melody lacking, cookie cutter music has taken music where it is choking for a fresh breath of real talent . American Idol and such make me gag in a bag. I've seen nothing in the last 25 years that will last 100 or 200 years like the Beatles, or Pink Floyd, or Led Zeppelin. Elvis, Sinatra, Crosby, Gershwin, Mozart, Beethoven will also be remembered. No one is going to remember Madonna or Lady GaGa. Honorable mention may include the Foo Fighters & Pearl Jam.
Sorry guys, I'm just very disappointed with this generation. Even my parents liked some of the Beatles and Beach Boys songs.
Not all metal fans do that. That is just a stereotype of what the typical metalhead would do.
