Originally had them in an order, of '70s, 80s, 90's, and 00's but if you go and add something else to it, it mixes it all up.
It appears my genres in order of importance are: reggae, singer songwriters, folk, punk, big band era/classics; interesting there's very little straight up rock-n-roll. Interesting that they'd have Niney the Observer, but not George Clinton's Atomic Dog. (??)
