There's an essential flaw in this system. You are not being rewarded for rating music that you like, but for music that you think *other people* would like.

Some of the tweaks like the random jukebox are trying to fix this, but it's pretty clear that if all we wanted to do was to get the maximum number of points for everyone concerned, we'd all get together and agree on one artist to vote for (say, Karlheinz Stockhausen), and there'd be no great profit for anyone doing anything else.

Their only hope is that people aren't smart enough to realize that and will in fact mark up "whey like" rather than "what they think others will like". But people are pretty good at gaming systems like that.

That's why this system is not *at all* similar to the Prisoner's Dilemma except that they're both problems in game theory. The essential problem of the Prisoner's Dilemma is that there *isn't* a stable equilibrium solution; but in this case there is more or less a stable equilibrium, the "All For Stockhausen" strategy.
