Katy Perry is on course for her second No. 1 album on the Billboard 200 chart, as her latest release, "Prism," should easily top the tally next week with her best sales week ever.
Industry sources suggest Perry's third album, which was released on Tuesday, Oct. 23, might sell around 275,000 copies by the end of the tracking week on Sunday, Oct. 27.
If she starts with that sum, she'll also log the largest sales week this year for a woman. It would surpass the arrival of Miley Cyrus' "Bangerz," which debuted with 270,000 at No. 1 a week ago, according to Nielsen SoundScan.
