Okay, so what if there was a darwinian music thing, where everybody would just throw their tunes in, and people just vote on songs as they come in. Every time at a certain interval, the system erases the lowest scoring songs so they disappear, never to be seen again. The top ten survive, and keep fighting against newer songs coming in. The score of songs degrades over time, so that it's impossible for one top rated song to dominate forever.
