How to attach background image for mp3?

Question

MP3

There are mp3 files that are planned to be distributed. How to attach an image to them, that is, to each of them? Namely - so that the user has a picture-cover when listening to this file (s). Well, you probably understand what I mean.
Not that this picture is found on the Internet when you click "find information about this artist on the Internet." And so that it is built into the file itself somehow. I think this is how it should work.

Answer 1
