2. Arcade Fire, "The Suburbs"
Three years after defiantly pumping their fists against "adult" establishments on "Neon Bible," Montreal indie rockers Arcade Fire discovered middle-class dissatisfaction on "The Suburbs," their sprawling third album. The shift in perspective paid off musically -- "Ready To Start" and "We Used to Wait" are some of the group's most immediate tracks -- as well as commercially, with the album hitting No. 1 on the Billboard 200 and receiving a Grammy nod for album of the year.
