The Sound of Madness is a Bingo-like challenge, consisting of 25 music-related prompts that can be interpreted freely. I gave a short explanation of how this challenge came to be in my post on Queen's Book Asylum. This challenge is mainly aimed at Fantasy readers, but you are absolutely welcome to interpret the prompts however it fits your reading. This is supposed to be a fun, no-pressure challenge. 

I don't have many rules. Personally, I'll only use 1 prompt/book, but you can go easy on yourself and use 2 or more prompts/book. As I said, the goal is to have fun and not to force yourself to finish it. Though I know I'll do just that myself... The only rule is that only books read in 2021 are eligible for the challenge.
