Katy Perry has set a new US chart record with her latest single, “Dark Horse.”

Billboard reports the singer claims the record for the most weeks at No. 1 in the 21-year history of Billboard's Pop Songs radio airplay chart, as “Dark Horse” featuring Juicy J tops the list for a fourth week.

Perry sets the chart record with a career total of 46 weeks at No. 1, passing Mariah Carey’s total of 45; Pink is third on the list with 32 weeks.

Billboard's Pop Songs radio airplay chart measures the most weekly plays at mainstream US top 40 stations.

Last week, “Dark Horse” also bested Perry’s mark for the most weekly plays (16,151) in the chart's archives, ahead of the 16,065 spins she snagged for "Roar", the lead single from her current album, “Prism.”

Perry will launch the Prismatic World Tour in Belfast on May 7, 2014.
