Okay well I'll start with the song that made me think of this. It's like in the top 5 of my favourite songs ever. It won a Grammy so I suggest giving it a chance! Hehe.
Tool - Schism (from Lateralus)
Lyrics
I know the pieces fit cause I watched them fall away
Mildewed and smoldering. Fundamental differing.
Pure intention juxtaposed will set two lovers souls in motion
Disintegrating as it goes testing our communication
The light that fueled our fire then has burned a hole between us so
We cannot see to reach an end crippling our communication.
