I have not, but I’ve thought of using Obsidian to dissect the work of a rap artist (e.g. Kendrick or Nas), which could be done similar to how you see the lyrics dissected on Genius.com but in a much more intense way. If you are looking for inspiration on how to implement it, the discussion around organizing the bible in obsidian might provide some insights.
How it would break down in my mind is:
- Note for an Artist links to a note for each album
- Note for each Album links to a note for each song
- Note for each song has links to
- Conceptual ties between songs
- Explanations of individual verses
- Subsections of the note with alternative interpretations
