How to find a problem-solving idea

Hello everyone,
I know this might be a very common question, but I want to ask how to find a problem-solving idea or a problem that can be solved in an industry which we generally don't know about. Like personally I am interested in solving problems in industries like music, content creators, and art. I try to talk to a few people, but I am not able to get the problem, either there is already a solution for it, or people are happy with the current solution, so there is hard to come up with any new idea or to build MVP.
How to start to find the idea when we don't have done anything specific in that industry like I had never made any music, but I have interest in it, I had created few contents but not much. So how to find it?
I can't work on something where there is no meaning in it, like just doing something for money, I know it's important, but I want to do it by having a vision that really solves the problem. I don't believe in copying other idea and twisting it a little, because ultimately we don't understand the problem.
Any help will be greatly appreciated :)
