This is only for promotional purposes, so you can show how good you are at arranging songs, not to make money. Then you put the MP3s on a new CD, but in a different order You decompile the CD (rip the songs to MP3 files) You purchase a CD of a music album you like. Rearranging a sprite sheet from a copyrighted game is absolutely derivative work or an infringement.Īnd 'promotion' does constitute a 'commercial use' even if it is a loss-leader and not designed to make money directly. If the original copyrighted work can be discerned in any way, then at best you have derivative work, if not a direct infringement. There is no such thing as 'change/transform it my X amount and it's okay.' That's a very common misconception.
