These days, Justin Timberlake sounds best in a romantic mode. His knack for love songs made "Mirrors" a hit, and it is what works so well for "Not a Bad Thing." While playing with similar backing as "Mirrors," this new single betters its already excellent predecessor because it's a sharper pop tune with a stronger hook and structure. Not to mention, Timberlake has fast become an iconic voice of his generation, and his delivery adds a sweet, sexiness to the classy affair. "Not a Bad Thing" is the kind of track that feels appropriate for both a wedding reception and a backseat make-out; it deserves to be a staple of summer radio.
