RIP, indeed. Surprised you didn't put Say Hello To Heaven on the list. Chris Cornell wrote it as a tribute to his friend Andrew Wood.
I never wanted to write these words down for you
With the pages of phrases of things we'll never do
So I blow out the candle and I put you to bed
Since you can't say to me now how the dog broke your bone
There's just one thing left to be said
Say hello to heaven
If there is an afterlife, I hope he gets to see his friend again and say more than hello.
