Pre-album singles “What Do You Mean?” and “Where Are Ü Now” didn’t sound all that much like the old (or, more accurately, young) Justin Bieber;even grouchy rock types had to admit the kid was sounding pretty good. Purpose fleshes out his new interests, getting deeper into contemporary R&B production tricks and adding thick dollops of tropical house to several key tracks, including the Skrillex/BLOOD co-produced breakup offering “Sorry,” which finds Justin in classic begging/pleading mode: “I just need one more shot at forgiveness.”.Teen idols rarely mature with such honey-kissed soul.
