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.

The new Billboard 200 chart's top 10 will be revealed on the morning of Wednesday, Oct. 30.

Perry's new album is led by the No. 1 Billboard Hot 100 single "Roar," which spent two weeks atop the list and has sold 3.24 million downloads. The song is currently the second-biggest song on U.S. airwaves, slipping from No. 1 to No. 2 on this week's Radio Songs chart. (Lorde's "Royals" bumps "Roar" from No. 1.)

Perry's last album, 2010's "Teenage Dream," debuted at No. 1 with 192,000 sold in its first week (her largest sales week yet). It went on to spend its first 57 weeks lodged in the top 40 of the chart, and has racked up 154 weeks on the tally in total. So far, the album has sold 2.8 million in the U.S.

"Teenage Dream" also famously became the first album by a woman to score five No. 1 singles on the Billboard Hot 100 chart: "California Gurls," the title track, "Firework," "E.T." and "Last Friday Night (T.G.I.F.)."
