Katy Perry's fourth studio album, Witness, debuted in June at No. 1 on the Billboard Top 200 and No. 1 on iTunes in 46 countries. The lead single, "Chained to the Rhythm," set the record for the biggest first-day Spotify streams by a female artist and is now certified platinum, with over 1 billion streams worldwide. Views on the accompanying video made her the most viewed female artist on Vevo. Follow-up singles "Bon Appetit" (whose music video was Perry's fastest viewed music video of all time, with 14.2 million views in the first 24 hours) and "Swish Swish" are both certified gold.
Perry made her Capitol Records debut with 2008's One of the Boys after signing to the label in 2007. She cemented her status as a global superstar with the follow-up album, Teenage Dream, in 2010. Prism, her 2013 album, debuted at No. 1 on iTunes in 100 countries and has sold more than 12.5 million adjusted albums worldwide. With the singles "Roar," "Firework" and "Dark Horse" each surpassing the 10 million threshold (including song sales and streams), Perry is the only artist to earn three RIAA Digital Single Diamond Awards. In her 10 years with Capitol, she has racked up a cumulative 18 billion streams alongside worldwide sales of more than 40 million adjusted albums and 125 million tracks. She is the most followed person globally on Twitter and the first to surpass 100 million followers.
