leader of gaga's fan club headed for disappointing sales week

Next week's Billboard Digital Songs and Hot 100 charts will be brimming with massive debuts, surging sales and some intriguing newcomers. A host of songs -- new and old -- will be vying for a position within both charts' top 10s.

Katy Perry's new "Part of Me," which was released digitally to retailers on Monday, Feb. 13, is heading for a debut sales week of around 400,000 to 420,000 downloads by week's end on Sunday, Feb. 19 -- so say industry prognosticators. That would mark the pop diva's best debut sales frame and the highest opening week for any act since Lady Gaga's "Born This Way" sold 448,000 on the chart dated Feb. 26, 2011, according to Nielsen SoundScan.

Perry premiered "Part of Me" in a performance on the Feb. 12 Grammy Awards ceremony -- much like how Gaga launched "Born This Way" a year ago on the Feb. 13 Grammys (two days after the single hit digital retailers). So effectively, Perry's "Part of Me" will sell around the same amount in seven days as Gaga did in three.
