As someone who listens to numerous genres but is also selective with what I listen to, I am confident that spotify simply doesn't cater to my demographic. They are really about scaling to the masses, as is evident by their move into podcasts and constants frontpage ads on new releases, as well as aggressive song caching. From a business perspective, I believe its simply not worth the compute/development effort from their side to have a recommendation engine on par with say Pandora.
