Some bands/artists to listen to?

I listen to the same ol' stuff over and over again. I would like
something new!
Some bands I like, to get a feel for my tastes and why I like them:
Sum41: old school, punk rock
Bayside: angsty lyrics
A Day To Remember: Pop/Punk Rock

And I'm sort of getting into electronica and dubstep, so any artists
in that genre will be helpful as well.

Thank you! :)
