I KNOW they have Arthur C Clarke's "Childhood's End" as an audio book because I gave it to someone a few years ago. Best book!
Otherwise, I'd suggest salsa---try Spanish Harlem Orchestra. You CAN'T fall asleep while bopping to salsa--it's just too much fun.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
