I would like to know if I use a free commercial use song and it says that I have to mention the author, where I have to do it so I do not get banned.
Also if you know of pages where there is no copy without naming (it is a piece of advice that I admit because I searched and found some but they are not of quality).
you can name it in a sector of the application with a about (would be the best) .. or put a txt in the programming files, where mentions the authors, remember that each license has its particular thing, it is important to know the type of license that you use to know in what it converts to your code ... for example if you use GPL license code forces you to have your code be open code
