I feel your pain. For the life of me I cannot get a playlist to match my preferences. Similar to your experience, I ask for Kansas and all I get is the same songs. For those who don't know, if you like Kansas, you are likely to like almost their entire catalog-- their "non-hits" are just as great as (or even better than) Point of Know Return, etc. Music I'd have to label "hard rock prog" exists, but what I've found has generally been on my own. Intuitively, AI should be *really good* at this. I will validate Rick's disappointing experience.
