I have a lot for this one too...If you're wondering, most of these are somewhere around the Punk Pop genre.
All Time Low (My favorite band of ALL TIME...Get it? Hehe...Erm...yea...) They have a dvd called Straight to DVD, aka STD...Coincidence? I think not! If you wanna watch it, the whole thing is on Vimeo. I'd watch in privacy with headphones because there is a lot of nudity (they cover it with Jack's face)
Paramore (Older songs)
Fall Out Boy (Older songs and some of the new)
Blink-182
NeverShoutNever
Green Day
The Foo Fighters
The Clash
My Chemical Romance ...Sad face :'( Don't touch me I'm not stable.
OOH! Woe, Is Me has an awesome cover of Hot n' Cold by Katy Perry. I haven't really listened to any of their other music though.
Mayday Parade
Panic! At the Disco
Simple Plan
30 Seconds to Mars
Boys Like Girls (Their old stuff...)
Cartel
Relient K
Pierce the Veil (I'm not into them that much, but they're good.)
Skillet
Three Days Grace
There are probably way more, but I can't really think of them right now.
