Good alt/rock/post hardcore 'couple' songs?

[rockinout1239]

I'm making a mixed CD for my boyfriend, and I need some ideas.

I have some songs already, but wanted some more suggestions

He likes bands like Tool, Switchfoot, Saosin, Papa Roach, Blink-182, Sum41, The Offspring, Nirvana, Rise Against, and Of Mice & Men... (etc)
If you know any songs by those artists that are... umm.. 'couple-ish' that would be helpful.

Whispers in the Dark - Skillet

 

[KennyMoutet]

Cage the elephant
Green day
Franz ferdinand
The killers (not very hardcore though)

 

[cbd]

Still Dreaming - Silverstien
You Had Me At Hello - ADTR
If It Means A lot to You - ADTR
Have Faith In Me - ADTR

those the only ones off the top my head that you haven't already suggested.
