This short but sweet EP offers nonstop good vibes with its reggae grooves, breezy songcraft, and white-boy raps. Backed by a horn section and soulful organs, Mraz celebrates the power of togetherness on “Freedom Song.” The explosive “San Disco Reggaefornia” trades the symbolism of the Eagles’ “Hotel California” for high-fives and medical-marijuana references. And “What Mama Say” is the ultimate Mother’s Day anthem, honoring maternal guidance with a funky beat.
