Cover art for All My Friends lyrics by Broken Social Scene

This is literally about their friends. "In all the songs they wrote instead, your ex-lover is not dead" is a reference to Stars, and "the duvets wish that they were still wet" is a reference to Metric. There are probably other references I'm not picking up on.

Also, it should be "little lives and massive dreams".

"There's a whore inside their bed" is a reference to the song "Hey" by Pixies

"must be a devil between us or whores in my head whores at my door whores in my bed"

You're both right. I thought no one would catch that, actually.
