i've changed the rules

cuz i can do it if i want to. i've decided, after musch deliberation on the thought of the movie nick and norahs infinite playlist, that i will allow the perfect playlist to be any length, other than one. or negative numbers. zer0 is fine, but only because i find it zen. but one is not a playlist. it's just your perfect song. which should be in the playlist. okay. just letting you know.
