You took the idea of the human genome project and applied it to music, right? Songs have a certain genetic code that allows you to group them together in various ways based on their attributes. Say I put in “Manic Monday” by The Bangles. Your algorithm will search the DNA of all the songs ever recorded, find the other ones annoying enough to fuel a genocidal dictator, and create a radio station containing just those songs. Then if you play “Everybody Wang Chung Tonight” by Wang Chung on that station, and I click the thumbs down icon, you’ll adjust your math so it doesn’t play any more songs by bands with fans who drive Fieros and carry nunchucks.
