Say I'm a fan of artist X who made a song Y. There is a sample used in song Y and I'm wondering where it is from.
A similar but perhaps slightly different question would be asking about an instrument used by artist X to make song Y.
Are these kind of questions on topic?
Yes, I believe these would be on-topic.
I would consider these specific, answerable questions, as long as they are specific to a time/song. Also, there are two such questions upvoted in the Area 51 proposal:
Let the community decide.
On Music: Practice & Theory they are off topic (Like Rory said) (The only other SE site concerning Music)
So, I would say yes, they should be on topic here.
