Frankly, that doesn't sound appealing at all as a discovery tool - unless I know I like the curator's taste, I'm probably not interested in his recommendations.
That's why the heavy rotation section in rdio that only showed popular music among your friends (which you should select carefully!) was so useful - if you had a circle of great tastemakers.
It's generated algorithmically based on your recent-ish listening habits combined with a bit of fairy dust, I believe they acquired a company that specialised in it.
It's pretty good at recommending songs to me that are similar to what i've been listening to, along with a few curveballs that encourage me to branch out, or throwbacks to older habits.
And while these algorithms work up to a degree at some point it's not useful anymore - especially if your taste is very specific and not dependent on obvious factors like genre or mood (I know, Echonest takes a lot more properties into account).
These days I see what feels like the same recommendations everywhere. Rdio solved this problem with good old fashioned human curation - and in contrast to Apple Music it's based on humans I want to follow, not some show host or editor that has to appeal to large crowds.
