I cheated and used Google. Apparently Tommy Dorsey died of choking to death in his sleep in 1956. So that seems pretty essential. Possible songs that might work: "Mr. Ghost Goes to Town", "If My Heart Could Only Talk", or just "I'm Getting Sentimental Over You" for obvious recognition.
That's also how Hendrix went in 1970 (obviously from different inducements) a lot of possibilities on that one too: "Night Bird Flying", "Are You Experienced?", "Cry of Love", "Manic Depression"
If you're going to be obsessive enough to seek out sound bites, this comes from a Wikipedia entry of MASH quotes:
""As I lay me down to sleep a bag of peanuts at my feet, if I die before I wake give them to my brother Jake." (From 'Crisis')"
I've never heard Mushroomhead, but apparently
this song is exactly thematically what you want. Hope it doesn't suck.
