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