Two of my favorite lines come from the same song:

We never did do much talkin' anyway
----------------
I gave her my heart but she wanted my soul

A really powerful song is American Pie. All the lyrics are good, but especially the last verse:

I met a girl who sang the blues
And I asked her for some happy news
But she just smiled and turned away
I went down to the sacred store
Where I'd heard the music years before
But the man there said the music woudn't play

And in the streets the children screamed
The lovers cried, and the poets dreamed
But not a word was spoken
The church bells all were broken
And the three men I admire most
The Father, Son and the Holy Ghost
They caught the last train for the coast
The day the music died

That just rips me up every time I hear or play it.
