Need Music

Hey, guys. So... I went on vacation and I had my mp3 with me the whole time, listened to it the whole time, and i realized: I don't really have alot of music, and what I do have I've gotten really kinda sick of. So I was wondering.... does anyone have some good music, or good bands, or people that they can recommend to me? Here's some of what I listen to:

Three Days Grace
Skillet
Linkin Park
Three Doors Down
Nickelback
Spill Canvas
The Used
Bullet for my Valentine
Taylor Swift
Plain White T's
Medic Droid
My Chemical Romance
Metro Station
Paramore
Hushsound
...and some stuff like that.

But if you have anything really interesting or good... please tell me! Thanks. :)
