My votes have nothing to do with exposure, but simply enjoyment. The only reason a song would have less exposure than any other is because when I like a song more.. I play it more, also yes, I DO appreciate and pay attention to the entire catalogue - just because my ratings/rankings tend to be more centered around certain eras/albums does not mean I ignore certain parts of the discography, it just means I don't like it as much. For god sakes man, stop trying to find a reason that everyone elses tastes don't match your own and accept that people like different things.
For the record, Sea of Madness has 156 plays since my last media reset, so it's hardly a case of under exposure.
