How can I check the music license?

Question

Copyright

Let's say there is one very old track (15-20 years old) and how can I check if it can be added to my game with ads for Google Play? And if I post a project with protected music, what will I get for it?

Answer 1

If in doubt, you need to look for the author of the music / song and ask him for permission. There are no services.
Or use at your own risk until you are punished. As a rule, this is a matter of time, because. there are always third parties who will complain to the right place.
Assume that there is copyright law. And you are clearly violating it.

Answer 2

Please contact RAO. They are practically monopolists. They also accept payment.
