I've posted an intentionally broad question on SE Music Fans. The question lends itself to, potentially, a large number of answers, but also to reasonably focused and concise answers, easy to browse through. However, one can imagine getting enough answers to become unwieldy. In this case, the question could be split off into more specific questions with the original as a hub.
Can answers be "ported" to a related question in a situation like this, or would they have to be recreated at the "branch" question by the author or author user?
