Not the biggest fan of emo and I don't have a selection right away, when I think of it, i'll edit this post.

Punk is a *bit* easier: Offspring, Ramones, Sex Pistols, Pennywise, The Clash.

out of those? Fall Out Boy
in general? Jimmy Eat World

Punk/emo? You just listed emo bands. Where's the punk?

The Offspring, Bad Religion, and Pennywise are main punk bands I listen to. Emo? Um...Emery? Dead Poetic and Underoath, I guess. Oh, and Thursday, when I used to like them a lot. They were here before any of these Fall out Boys and My Chemical Romances. Bow down.
Beloved were good, but they broke up.

Thursday is amazing.

Yeah the new Thursday, "Counting 5, 4, 3, 2, 1" is f--ing fantastic.

Taking Back Sunday n' From First To Last is the bestesets' of los emos
