This enigmatically titled album may be Ed Sheeran's debut, but this young Brit has had buzzy written all over him for years. + has all the bells and whistles that earned him that buzz: beat-boxing over acoustic guitars; sweet crooning of lyrics riddled with nostalgic pop culture references (see the conversational "Wake Me Up"); beats culled from rock, coffee-shop pop, country ("Give Me Love") and a whole lot of Justin Timberlake's hip-pop songwriting book. But the plus of +? The tender, loving earnestness with which Sheeran and his feathery tenor kiss every song.
