Katy Perry's "Part of Me," the lead single from her "Teenage Dream" deluxe edition, "The Complete Confection" (due March 27), bounds onto the Nielsen BDS-based Pop Songs radio airplay chart at No. 21, marking her highest debut and the chart's best bow since Lady Gaga's "Born This Way" launched at No. 14 a year ago this month.
Early estimates peg "Part of me" as selling north of 400,000 downloads in its first full week of availability, setting up a potential No. 1 debut on this week's Billboard Hot 100. See Part of me below.
