I'd have to pick Robot Boy or Somewhere I Belong, actually anything on Meteora... Wow... Now that i think of it that album is actually really depressing... But the music was still A-Rate :)
The song that could describe a part of my live is From The Inside, I won't waste myself on someone who betrayed me, so if someone make me feel that way I won't waste my time on him/her.
It's a bit unusual that you don't like anything of Meteora, thanks to this album Linkin Park is famous around the world... Well, somewhere I belong it's another song that I'd choose to describe a part of my live like you :)
"Waiting For The End"
I think that most describes my life is to leave out the rest
Most 4 song In the end, Crawling, Numb, by myself,
Numb, in the end, one step closer and faint
A canção Linkin Park que descreveria a minha vida seria breaking the habit
