This is my first ever contribution to a meta in all the SE sites that I participate in. You will see that I'm fairly new here so I don't know the lie-of-the-land very well, but I hope this is seen as constructive criticism from a newbie.
The point is that I check the site virtually every day and, if I'm lucky, there might be 1 or 2 new questions since last time. Almost without fail, the questions have little interest for me and I can't answer them. I consider myself to be a huge Music Fan so it seems bizarre that I am bored by a site for music fans!
Given the lack of questions, I think there is something to be said for easing up on the "off topic" police and letting a few unpalatable questions through.
I think I can understand why there's a dislike of "identify this song" questions. I used to regularly read the "Notes and Queries" site on guardian.co.uk and that deteriorated into "can you name this film". Maybe the way forward is to allow "identify this song" when it is even slightly richer than a simple question. If the numbers start to get overwhelming then there's no reason not to shut it down by making the criteria a little harder to meet.
I'd just like there to be more questions that are either interesting in themselves or generate an interesting answer. At the moment, I'm not seeing a lot of either.
