In this episode of Anatomy of a Song, I compare two generations of SM Entertainment girl groups by stripping back the vocals of Girls' Generation’s “Mr.Mr.” and Red Velvet’s “Queendom.”

Both songs represent very different eras and approaches to SM’s signature sound. “Mr.Mr.” leans into layered harmonies, fuller vocal projection and dramatic build-up, while “Queendom” takes a lighter, smoother and more restrained approach.

By isolating the vocals, I break down how each group handles tone, blend, control and delivery — and what these differences reveal about how SM’s girl group vocal style evolved over time.
