The World's Greatest Britney Spears Tribute is actually the cash-in of cash-ins since it simply combines Big Eye's two existing Spears tributes, which were already paltry entertainment cardboard. World's Greatest wisely chooses only the biggest hits for its reversion, and even if the studio musicians performing here can't imbue any vitality into "Oops! I Did It Again," "Baby One More Time," and "I'm a Slave 4 U," the songs squeak by on the songwriting that originally made them hits. Unfortunately, there's little else worth mentioning here, even for Britney diehards. And where's "Stronger," anyway?
