Former preteen star Sammie’s I’m Him EP is a total distillation of his slick sound. After early success led to a reevaluation of his priorities—and a step away from music—the Florida native returned to the R&B charts with a meticulously fine-tuned and gratifyingly nostalgic vibe. The title track, with its syncopated beats and hairpin vocal runs, nods to ‘00s Usher, while the finger-snaps and crystalline harmonies of “Sheets” is a pure Boyz II Men homage.
