I like this song, and I may have or may not have posted it before. It has a sad connotation to it (and was used appropriately in "P.S. I love you"), but a good song nonetheless:

"If I Ever Leave This World Alive"
Flogging Molly

If I ever leave this world alive
I'll thank for all the things you did in my life
If I ever leave this world alive
I'll come back down and sit beside your feet tonight

Wherever I am you'll always be
More than just a memory
If I ever leave this world alive

If I ever leave this world alive
I'll take on all the sadness
That I left behind
If I ever leave this world alive
The madness that you feel will soon subside

So in a word don't shed a tear
I'll be here when it all gets weird
If I ever leave this world alive
So when in doubt just call my name
Just before you go insane

If I ever leave this world
Hey I may never leave this world
But if I ever leave this world alive

She says I'm okay;
I'm alright,
Though you have gone from my life
You said that it would,
Now everything should be all right

She says I'm okay;
I'm alright,
Though you have gone from my life
You said that it would,
Now everything should be all right
Yeah should be alright
