Not that I plan on getting famous, but just hypothetically, lets just talk about the first song, what do you think I would have to change in order for me to be able to safely say, it's a different song?
And Nsmadsen, I agree with you. I am trying to learn to make music by starting with remixing my favorite songs, and then I hope to make my own completely original later.
On a second thought. Is it safe to say that as long as I don't sell my game, I can use a remix of another song in my game and not worry about people trying to sue me? Assuming the game happens to become famous-
