I almost exclusively listen to prog rock (e.g. this and this) and prog metal (e.g. this and this). I cannot stand the endless repetition in most genres (e.g. 20 seconds of melody/harmony/rhythm repeated to make a 3 minute song); most prog music is substantially less repetitive than most genres.

I find new prog music through Wikipedia and ProgArchives. Usually the best prog albums (yes albums, not just individual songs) have the highest rating and listenership. Ordinary people do have a sense for good music, if only they were given the opportunity to hear it.
