Katy Perry's new song "Roar" is off to a roaring sales start, with industry forecasters suggesting it will move around 450,000 downloads by the end of the tracking week on Sunday (Aug. 18).
Meanwhile, fellow diva Lady Gaga is also off to a handsome launch with her new single "Applause." It's heading for a bow of perhaps 200,000 to 225,000 downloads.
Monday, Aug. 12, there were early indications that both "Roar" and "Applause" could sell over 400,000 downloads. At the time, industry sources theorized that, considering both artists' stellar track history with digital song sales, a robust first-week for the two acts seemed likely.
However, once the songs went on sale, the forecast changed. Still, we have four more days left in the tracking week -- so anything can happen
