It should be a real ease to create good music discovery/curation for spotify since they acquired the echonest. It it really simple to add similar music to what you are currently listening to, too a rolling playlist. Unfortunately, the way they fo it feels like promotion instead of individual curation. It was easy when I created trushuffle some 8 yrs ago (before Spotify aquired echonest) and it should be even easier for a multi billion company.
