It can be a number of songs

It can be a line of a song...

Whatever it is - what are your favourite lyrics?

I have a lot. But I love these lyrics in a song called "In a Market Dimly Lit" by mewithoutYou:

"I wrote a little song for you
with a memory I'd borroed put to words that didn't rhyme
to repeat what you already knew
as the stones thrown at your window tapped a syncopated time
you kept a distance out of fear you'd break
but what good's a single windchime, hanging quiet all alone?
The music our collisions would make
is a sound that turns the road-that-leads-us-back-home
into home...

The music our collisions make!"
