I can't imagine anyone employing people to sit a desk all day, looking at the music you like and then working out what other music you would like. For a start, no human would have that massive encyclopedic knowledge of songs and genres, including album tracks etc.
Certain jobs/processes are only possible and have been created because of AI. I suspect this will be the better use.
Self driving cars, where one accident can be analysed and then the scenario be exported to all the other self driving cars so they don't make the same mistake, unlike human drivers who all seem to make the same mistakes over and over again and never learn from either themselves or others.
