I've thought of a lot of different ones at different points in my life. Songs to make up a soundtrack to your life and such. But for the purposes of this thread, we're just focusing on your funeral. I admit this is a bit of a corollary to the theme song thread, but I thought it'd be fun.
At this moment in time, I can only think of one that immediately stands out for my own funeral. It's a cover of a Rolling Stones song, and you may remember it (or at least BG will remember it) as the song from the end credits to The Big Lebowski.
Feel free to suggest songs for others' funerals as well!
