Plain White T's scored a mainstream breakthrough with the No. 1 hit "Hey There Delilah" in 2007. While "Natural Disaster," the first single from their current album ("Big Bad World") failed to live up to that crossover smash, it also veered in a more rock-oriented direction. The follow-up, "1,2,3,4," returns the group to the acoustic love song formula that catapulted it to worldwide success. With a light strumming guitar as the main backdrop, lead singer Tom Higgenson offers a heartfelt vocal as he earnestly writes a wish list for his love: "Give me more loving from the very start/Piece me back together when I fall apart." While sentimentality might be gush in most hands, Plain White T's balance it with enough musicality to add weight —and more important, to get folks singing along.—Chris W. Woods
