Songs like this make me miss making mix tapes (eff yeah alliteration).  I'm still such a sucker for songs about unrequited love... I'm thinking second to last track, leading into Dashboard's Acoustic Hell on the Throat...

Florence and The Machine - Cosmic Love

A falling star fell from your heart and landed in my eyes
I screamed aloud, as it tore through them, and now it's left me blind

The stars, the moon, they have all been blown out
You left me in the dark
No dawn, no day, I'm always in this twilight
In the shadow of your heart

And in the dark, I can hear your heartbeat
I tried to find the sound
But then it stopped, and I was in the darkness,
So darkness I became
