I suspect that the reason Discover Weekly is so much better than radio, and is only available once per week, is that it's computationally costly. Either way, radio-from-artist or radio-from-song can't utilize your listening history. It's quite possible you listen to an artist for different reasons than the reasons most people listen to that artist - in that case, you will get recommendations based on the majority's reasons. You would expect personalized recommendations to have potential to do much better, and I'd argue that's exactly what we see with DW.
