Part of Me (Katy Perry song) [SEP] Introduction
A dance-pop and power pop song with a distinctive house beat, it has been compared to Perry's 2010 singles "Firework" and "California Gurls". Its lyrics describe a female protagonist who declares herself as unbreakable and strong following a break-up. Many critics theorized that the lyrics addressed Perry's divorce from Russell Brand, although Perry stated it was not about him since it was written in early 2010. "Part of Me" was a commercial success. It was the twentieth song to debut at number one on the "Billboard" Hot 100, Perry's seventh number-one single on the chart, and her ninth consecutive number-one single on the "Billboard " Hot Dance Club Songs chart.
