Songs to learn on guitar?

I've been wondering which song I should learn on guitar, but I dont really know. Can anybody suggest one? I'll list some songs I already know how to play, so you can get somewhat of an idea of what I play.

Afterbirth - from first to last
Mothersound -...

from first to last
...and we all have a hell - from first to last
Adams song - blink 182
Josie - blink 182
Dammit - blink 182
I caught fire - the used
No more sorrow - linkin park
Given up - linkin park
A place for my head - linkin park
Nothing left to lose - american hi-fi

Thats what I can think of at the moment..but yeah, you get it. I want to play something that sounds good, and is kind of challenging, but easy enough for me to play, im not really that good.

Thanks!

Peaches and Cream - JBT is a fun one.
Nothing Else Matters - Metallica. Really easy and very catchy
My Sundown - Jimmy Eat World. Very nice, only 3 chord changes, chorus is fun
Devine Intervention - Taking Back Sunday - Also very easy, but challenging when you first start at guitar
Hey There Delilah - Easy and everyone knows it so its a fun one to play.

Have fun :D
