While nobody can quite match Michael Bublé’s effortless-sounding phrasing, the modern crooner’s unruffled cool has spawned disciples across many genres. Observe the jazzy delicacy of Madeleine Peyroux and Melody Gardot, or the woozy soul smoulder of Amy Winehouse. Even unlikely descendents like Family Guy creator Seth MacFarlane and the Frozen power ballad “Let It Go” take loving cues from Bublé’s in-built emotional finesse.
