Rick & Morty’s song “Terryfold,” by the Seattle duo Chaos Chaos, just entered the Billboard charts 10 days ago – but, is it a fluke? Or have they got what it takes to really make something?

Their newest single “Dripping With Fire” just dropped today, but you can still listen to ‘Terryfold’ again below! And read Chaos Chaos’ interview with VICE here.
