Are questions about evaluating music and comparing generes on-topic here? Example:
What are the similarities between Baroque and Minimalist music?
This question will involve history to a great extent, but the focus of the site is on making music. This strikes me as a music-appreciation question, more suitable to a music listening site. (Coming soon...?)
Should these be on-topic here? If not, where can such a question be asked? (There's already one very good answer to the linked question.)
