Sorry, I'm newfag in gamdev, so I don't know, which way is the best...

I do anything myself, except music (music is free-to-use from account of one guy at free music and sounds site)

Would it be right if I put "Music: [this guy name]" and a link to his account? (Inside the game as a text)

And I should write his link and name on itch .io when uploading game, I guess?

(Sorry for my English, it's my second language)
