I am of the opinion that these particular questions are indeed on-topic; they eliminate a lot of the issues that we originally had with identification requests by being explicit and very narrow in scope.
However, I also believe that they make for poorer questions (and answers) in general. It may be nice to figure out what the name of some BGM is playing in the background so you can purchase it later, and it may be nice to have some closure on where a scene from an episode came from. However, I personally don't feel satisfied when I see a similar pattern of answera similar pattern of answer as we did with original identification requestswith original identification requests. This may be worth a separate discussion, but for now, identifications for music and scenes is on-topic.
