itch.io

I have a question regarding music usage in the jam. Basically, I don't know how to create music, but If I were to make a game in the jam, is it possible for me to use music from an old game? I mean, I would put the fact that I don't own the music in the credits, but I'm not really sure if this can even be done on itch.io, even if it's a free game. Thanks
