Good Music on Instagram: "In this episode, Metallica (the legendary heavy metal band) join comedian Billy Eichner in a car to sing along to songs—including Rihanna’s Diamonds. It’s a humorous and unexpected contrast: a band famous for intense thrash metal screaming “shine bright like a diamond.” Fans loved this because it showed Metallica’s lighter, fun side. They weren’t performing their usual heavy riffs, just singing pop karaoke and joking around with Eichner."
