Successful auto-playlisting is going to vary on the demands made. There is no 100% music (or any creative output) recommender because everyone feels differently about what 'energy', 'easy', 'powerful', 'touching', and 'rock' all mean, and to each person individually. These terms are meant to, and always will be, necessarily ambiguous; and that is how these terms work best. AI currently cannot 100% give you a track without drums even if you check the 'no drums' box (because along the way one track with drums was put in the no drums box). Incidentally I've used various searchers (now referred to as) AI for years to try and find tracks requested by clients, it remains somewhat helpful though unable to compete with a human first listening to the human making the request. AI is improving, but it is going to be beyond our lifetime before it replaces communication, human to human, eye to eye. Until AI knows what it means to be human, so it shall remain.
