The bottom comment is based on an old '60s "head" joke that may or may not have survived but I like the idea of basing all criticism on the four criteria in the avianism tweet. "The painting had style and creativity and it might endure but for the absence of the dopamine factor." Or, "what this song lacks in originality, instant-classic appeal, and, let's face it, panache, is more than compensated by the awesome head rush it gives you."
