The idea of big fun suggests the existence of little fun, and Lady Gaga is now the kind of pop star who can do both. “Just Dance.” Meat dress. Being carried down the red carpet at the Grammys inside an egg.

“Mayhem” puts the lie to that idea: Brash, squirmy, full of detailed grooves and expertly crafted hooks, it’s a winning reclamation of her trademark sound — her best since 2011’s “Born This Way” and precisely the album you’d want her to drop before headlining Coachella, as Lady Gaga will do next month.

On the new Billboard Pop Shop Podcast, Katie & Keith are marveling at the high-wire act Gaga pulled off with her seventh studio album.
