For the music application, Max Cooper uses items that appear in the OEIS catalogue pretty heavily. IMO, his works sound amazing. Tracks like Aleph 2 (https://vimeo.com/367747083) or Fibonacci Sequence (https://vimeo.com/991635293) stand out as immediate examples.

For something more mainstream even Tool lean into the Fibonacci sequence theme with Lateralus, almost to a meme level.
