I have a whole playlist of songs I've been making that I want to ctb to, but I have different sections in the playlist for different methods if that makes sense. You know, cause for overdose and SN you want something calm, but something energetic and lively but sad for jumping (if that makes sense).
One that I really like is As the World Caves In. Not about suicide, but about he end of the world during a nuclear war. It's nice and peaceful for some reason and calms me down, and also kinda sad.
"And here it is, our final night alive
As the earth burns to the ground
Oh girl, it's you that I lie with
As the atom bomb locks in
Oh girl, it's you I watch TV with
As the world, as the world caves in"
