lets say a robot was capable of distinguishing various instruments and singing styles. if it tried to guess the genrres of various songs, could it do so based on only this information? or is it too loosely / culturally defined for it to be possible?
what tends to happen is, the company will claim that it's doing this by sound only, but actually it's probably relying heavily on the metadata, and the market data, looking at demographics of who's listening to it
