(For the general genre tag, see the question Usage of the [genre] tag.)
For which questions do we want to use specific genre tags?
Example tags: rock, jazz, electronic-music, rap, pop, blues, hip-hop, cyberpunk, deep-house, house, ….
Obviously for questions about the genre itself, right?
Anything else? For example, questions about a specific musician that happens to make music that belongs to the genre, or questions about a specific work (e.g., a song’s meaning) that belongs to this genre?
(Background, and possibly food for this discussion: I tried to remove the jazz tag from this question about a specific work.)
