Jessie J's "Price Tag," the second single from debut album "Who You Are," is designed to make the listener move and then be stuck in his or her head for days afterward. The U.K. singer/ songwriter has a history of crafting über-catchy pop tunes, and "Price Tag" has the same ineffable quality engrained in its melody as Miley Cyrus' 2009 single "Party in the U.S.A.," which Jessie J co-wrote. "Price" also has an equally simple message, as Jessie explains, "Money can't buy you happiness," while utilizing her powerful voice. The edges of B.o.B's fluid rap verse are softened by a guitar riffing in the background, providing a retro feel that lets Jessie J "Take it back in time/ When music made us all unite." The uptempo bebop drum beats give "Price Tag" a dancehall anthem flavor, and if Jessie J does indeed "wanna make the world dance," she may be on her way to succeeding.
