or do you think music doesn't need to be categorized at all?
it can be fun for entertainment purposes but no matter what system you use, it will break as soon as you add more than 2 songs. i think it's actually music's job to break these systems. if it weren't, then where's the fun, you know. i think often people who don't make music like to think these systems are somehow supposed to be reliable, which makes for an interesting game of cat and mouse which the mouse will always win
