Sad songs (say so much), by Elton John. It says so much. Paranoid, by Black Sabbath. Much sadness is always evoked. On a more serious note, I think everyone who has ever played Fallout 4 knows how depressing "One More Tomorrow" (Frankie Carle) and "End of the World" (Skeeter Davis) are... Not so much while desperately trying to kill a behemoth with mini-nukes, but... Black (Pearl Jam) and Hurt (Johnny Cash cover) as well.
