I came across a question from 2011 that, were it not so old, I would flag for migration to Music Fans.¹ Is there a rule or rule-of-thumb for this?

• The question has been here a long time, and it's not hurting anyone. Leave it be. Don't create extra work for the mods.
• Our priority is to keep the site as well organized as possible, and that's a team effort. Flag anything you feel appropriate so it can get checked out.
• Something else?

¹_{Is there some symbolic meaning to breaking all the instruments during or at the end of your music video?. It was last active in 2016.}
