The 'A Star Is Born' track ties 'Just Dance,' 'Bad Romance' and 'Born This Way.'

Lady Gaga ties a personal best atop Billboard's Digital Song Sales chart, as "Shallow," with Bradley Cooper, leads the list for a fourth week.

Gaga previously topped the tally for four weeks each with three prior No. 1s on the chart: "Just Dance," "Bad Romance" and "Born This Way."

Here's a recap of Gaga's six Digital Song Sales No. 1s, and their weeks spent at the summit:

"Just Dance," feat. Colby O'Donis, four weeks, beginning Jan. 10, 2009

"Poker Face," one week, April 11, 2009

"Bad Romance," four weeks, Dec. 5, 2009

"Born This Way," four weeks, Feb. 26, 2011

"Million Reasons," one week, Feb. 25, 2017

"Shallow," with Bradley Cooper, four weeks (to date), Oct. 13, 2018

Meanwhile, Gaga and Cooper's soundtrack to A Star Is Born, starring Gaga and Cooper, spends a third week at No. 1 on the Billboard 200 albums chart, setting a new highpoint for Gaga, as it passes Born This Way, which ruled for two weeks in 2011, as her longest-leading No. 1 set.

On the streaming, airplay and sales-based Billboard Hot 100 chart, "Shallow" slides from No. 10 to No. 14, after reaching No. 5 two weeks ago. Still, it surges by 50 percent to 17.9 million in all-format radio audience in the week ending Oct. 28, according to Nielsen Music, as it scales the Adult Pop Songs (18-14) and Adult Contemporary (25-19) airplay charts and debuts at No. 34 on Pop Songs.
