I agree. Of all the bands that have impacted what we call "emo", Jimmy Eat World has probably done the most.
On a different note, I feel like someone dropped the ball in not having Weezer on this list.
I disagree with Weezer.
"Pinkerton" is the only album that could remotely be considered emo, and the 90s had too many important bands to go with a mostly-power pop group.
