Britney Spears is certainly back "in the center of the ring" with her new hit album "Circus." As one of the most popular and notable songs on her newest release, "Circus" pulsates with a sensual and irresistible beat that is intensified by breathy vocals and a velvety beat. Britney has a history of relatively weak and repetitive lyrics since her debut album "…Baby One More Time," so the lack of creativity in her self-centered words of "Circus" should shock few listeners. Instead, the simple words allow enthused fans to focus on the strong and flowing beat and ignore the simple, toneless melody. Regardless, her claim that she "calls the shots" is not entirely off the mark, as her voice exudes calm authority and self-assurance, accompanied by an air of mystery. The catchy beat and sensual vibe are what make this track just as fun as a circus performance, and listeners are sure to experience a tempting urge to move. As Spears sings, "there's only two types of people in the world/the ones that entertain and the ones that observe," and we can certainly expect Spears to continue to be the type that entertains with catchy pop tunes like "Circus."
