It is my belief that everyone (irrespective of age) should have a roster of songs in writing (among other financial wills), should their existence be cut short unexpectedly (or expectedly). I pick my iTunes playlist when I'm alive, and I expect no different on the other side. Nothing worse than Leonard Cohen's "hallelujah" blasting at your funeral. Sorry, but Shrek comes to mind.
Never forget that your time is objectively limited, while your money/wealth is subjectively limited.
Some of mine (in no particular order):
M83 - Outro
Schubert - Ave Maria
Hans Zimmer - Time
Zach Hemsey - The Way (Instrumental)
Ludovico Einaudi - Fly
Post yours below -- it could help others add to their list.
