I think I've posted this in several song-related threads before,
but for me, the song would be:
Stuck In A Moment You Can't Get Out Of by U2.
It reminds me too much of a good friend of mine who took his own
life a year ago. The last few lines are particularly
haunting:
And if the night runs over
And if the day won't last
And if our way should falter
Along this stony pass
It's just a moment; this time will pass
Another one would be Dionne Warwick's That's What Friends Are For.
I was in the primary school choir back in primary school, and we
sang this song for the graduation ceremony. It's a really simple
and beautiful song regrading friendship. Even after 10 years I can
still recall some of it:
Keep smiling, keep shining
Knowing you can always count on me for sure
That's what friends are for
In good times and bad times
I'll be on your side forevermore
That's what friends are for
