Are artists able to copywrite their voice? Are we heading for a bureaucratic nightmare? If I find an artist to be questionable, it is "ethical" to consume generated music of this nature based on their prior work? Are we on top of a slippery slope and going downhill towards the obvious next steps? Can we even trust anything at this point?
