I have never done a game jam before, so I used some music from a site, which the rules allow as long as I provide credit. I got the music from pixibay so would saying at the end of the game "music provided by pixabay" be enough?
I would probably say if its the main track then something like "Main track by (author) from pixabay". You might also be fine if you just include that on the game page or in a sub menu inside the games menu.
