Lady Gaga’s Joanne album is on course for a big jump on next week’s Billboard 200 chart, according to industry forecasters. Sources suggest the former No. 1 set could vault back into the top five, and possibly to No. 2, following Gaga’s halftime performance on the Super Bowl (Feb. 5).

Prognosticators suggest Joanne could earn over 70,000 units in the week ending Feb. 9 -- up from the 8,000 it scored in the frame ending Feb. 2 (according to Nielsen Music). On the latest Billboard 200 chart (dated Feb. 18, reflecting the Feb. 2-ending tracking week), Joanne slid 59-66.

The Billboard 200 chart ranks the most popular albums of the week based on multi-metric consumption, which includes traditional album sales, track equivalent albums (TEA) and streaming equivalent albums (SEA). The top 10 of the new Feb. 25, 2017-dated Billboard 200 chart -- where Joanne could zoom to No. 2 -- is scheduled to be revealed on Billboard’s websites on Sunday, Feb. 12.

During the halftime show, Gaga performed a number of her most familiar hits, alongside a new song, “Million Reasons,” from Joanne. The album was released last October, and debuted at No. 1 on the Billboard 200, granting Gaga her fourth chart-topping set.

It was earlier reported that Joanne surged in digital sales on the day of the Super Bowl, racking up over 12,000 downloads sold that day (up 1,077 percent). Overall, based on initial sales reports collected for Sunday according to Nielsen Music, the diva sold about 150,000 digital albums and songs in the U.S. on Feb. 5 -- an increase of a little more than 1,000 percent compared to the previous day, when she sold around 15,000 digital albums and songs.
