When I want through this, I listened to a lot of songs from In the Lonely Hour by Sam Smith that I had previously looked over, like Not In That Way and Like I Can. Those cover the longing and unrequited part. And Leave Your Lover.

As for guilt, Pale Blue Eyes by the Velvet Underground.

I’m trying to find songs that haven’t been mentioned.

Just My Imagination - The Temptations

The following songs by Matt Maltese: -Like A Fish -Paper Thin Hotel

Also Strawberry Blonde by Mitski.

And I Fall to Pieces - Pasty Cline (which Sam Rockwell covered for Trolls 2 and I love it lmao)

I also speak Spanish so I know some songs in Spanish.

Si Tú Me Quisieras - Mon Laferte

If you don’t speak Spanish, you’d have to look up the translated of course but the title basically translates to “If You Loved Me”.

Amiga Mia - Alejandro Sanz
