Show HN: Unlock Tracks from an Album Based on Its Popularity

This is an interactive site I made for an electronic music EP. It's powered by an "growth engine" I'm working on that let's you define the social ecosystem around a work of art [1]. The tracks get gradually unlocked as the previous ones get more plays, shares and the artists followings increase.

This is still in very early stages, so I would appreciate some UX feedback. I want to make the template as simple as possible, preferably without text or explanations - keeping it deliberately playful and explorative.
