Not strictly production related, but this is the most relevant place I guess. Basically, I'm contemplating doing a mixtape. I have a few beats in mind. But as these are all instrumentals from tracks already released (for example if I were to use a beat from a Jay Z album), I'm sure soundcloud stops you uploading them for copyright reasons. Is there a way I can get around this? Like changing the bpm or someshit? Would like to do one, but not uploading it to soundcloud kills a huge amount of listeners.
