Possibly an unpopular opinion (which is ironic), but I think this could do with taking popularity into account. The vast majority of music out there is generic landfill at best, and just outright bad at worst. I think once you've done the first pass and got the sonically similar songs there should be some kind of filter which prioritises tracks with higher listener counts which would inject some 'wisdom of crowds' into the decision making. It would be a pretty cool feature to then be able to have this setting on a slider with obscure at one end and popular at the other.
