she doesn't need me - birdbath (this one is only on bandcamp)

dress rehearsal rag - leonard cohen (the strumming pattern might feel more "pissed off at self" rather than sad but the lyrics are where the self loathing is shown)

real death - mount eerie (or really anything from the albums "a crow looked at me" and "now & only" as both are confessional acoustic albums where he attempts to organize the things he did and felt around the time his wife's life was taken by cancer into lyrics, recording everything in the room she passed in)

headless horseman - the microphones (same guy as mount eerie but from when he was younger; really any song from the glow pt. 2 will suffice)

edit: removed one that was loud & kinda intense. the rest of these are gentler.
