Gaga makes a Super Bowl-fueled flight to the summit for her second total week on top.

Lady Gaga is the top musical act in the U.S., rocketing from No. 61 to No. 1 on the Billboard Artist 100 chart (dated Feb. 25), following her Super Bowl LI halftime performance on Feb. 5.

The Artist 100 (which launched in July 2014) measures artist activity across key metrics of music consumption, blending album and track sales, radio airplay, streaming and social media fan interaction to provide a weekly multi-dimensional ranking of artist popularity.

Gaga gains by 1,219 percent in overall activity, with digital song sales contributing her greatest share of Artist 100 points (46 percent), followed by album sales (40 percent). As previously reported, Gaga's current single "Million Reasons" roars back onto the Billboard Hot 100 at a new high of No. 4 (tying for the highest re-entry in the chart's history) and returns to the Digital Song Sales chart at No. 1, up 1,334 percent to 149,000 sold in the week ending Feb. 9, according to Nielsen Music (also aided by 69-cent sale-pricing in the iTunes Store).

On the Billboard 200, "Reasons" parent album Joanne jumps 66-2, gaining by 818 percent to 74,000 equivalent album units.

Gaga earns her second total week atop the Artist 100. She first led the Nov. 12, 2016-dated list, when Joanne debuted atop the Billboard 200.

Big Sean returns to his No. 2 Artist 100 peak, blasting from No. 21, as his new album, I Decided., launches at No. 1 on the Billboard 200 (151,000 equivalent album units). The rapper makes a 397 percent overall gain, with album sales accounting for 48 percent of his total Artist 100 points.

Rounding out the Artist 100's top five, Ed Sheeran dips 2-3; Bruno Mars bumps 6-4; and The Weeknd descends 4-5.
