I'm not a fan of sorting shit by decades as there's a lot of residue (ie early decade carries a lot of stuff from the previous years and the latest part is usually transitional) but aren't the 80s by far the best decade for music? Can't think of a genre where the 80s isn't the peak, with the 70s probably the main competitor.
2000s were solid but the rise of autotune killed the mood.
2010s had good electro shit but overall the quality has dipped. No clue on what's new now.
