From this thread [webmasterworld.com] comes a couple of interesting quotes to start with:
For me, I've been resisting the idea of choosing a track for the obvious reason that I don't want to think of my funeral! But two songs have worked their way into my head as possible candidates to be played:
1. Marvin Gaye - What's Going On. The lyrics go something like "Brother, brother... there's too many of us dying". It's a really smooth piece that might work well.
2. Philip Glass - It Was Always You, Helen. Came across this recently (it's from the Candyman soundtrack) and had to download it. Lovely piano verses and powerful organ chorus.
I'm sure though that there must be more suitable choices. (A long time ago I was just going to play my favourite records, but I don't think Tangerine Dream and Yes would go down too well!)
So what would you choose, and why?
