Lady Gaga's new single "Perfect Illusion" appears headed for a debut in the top 20 of the Billboard Hot 100 chart.

Based on industry forecasts, the song could sell 100,000 downloads in its first week. It also could draw approximately 18-20 million in radio audience and 6 million U.S. streams, based on Billboard projections according to preliminary Nielsen Music data. Those figures could add up to a top 20 debut for the song on the Hot 100, which blends sales, airplay and streaming data.

"Illusion," released to radio at 11 p.m. ET on Sept. 8, and shortly after to streaming and retail services, will make its entrance on the Hot 100 dated Oct. 1; highlights of the chart will post on Billboard's platforms Monday, Sept. 19; the entire chart, and all rankings, will update the following day.

The lead singles from Gaga's previous two solo pop albums both logged lofty launches on the Hot 100. "Applause," from ARTPOP, soared in at No. 6 in 2013, before peaking at No. 4, and "Born This Way," the title cut from her 2011 album, opened at No. 1, where it spent its first six weeks, marking the longest reign of her three leaders. "Applause" began with 218,000 downloads sold and "Born" 448,000, the latter sum representing the seventh-best digital sales week for a song to that point, and the third-biggest debut.
