"MILLION" FIRES UP GAGA AT iTUNES; TOUR ANNOUNCED

"Million Reasons" was the only song from Joanne that Lady Gaga chose to include in her Superbowl LI halftime show. The stadium was illuminated by lighters, phones and light-up swag, as crowd members swayed with emotion, during the Interscope star's powerful (and nearly operatic) delivery of the ballad. This was a real moment.

The current single immediately surged up the iTunes chart, where it continues to sit at #1 this morning.

"Born This Way," "Poker Face," "Bad Romance" and "Just Dance"—the other songs she sang during the Super Bowl halftime show—were still in the iTunes Top 10 this morning. In fact, at press time, she had 24 songs in the Top 200.

Fans continued to buy her albums overnight as the deluxe edition of Joanne sat at #1 with the standard version coming in at #3. The two editions of The Fame Monster were at #5 and #6; Born This Way was #8 and The Fame sat at #11. Then there was Born This Way (Bonus Track Version) at #19 and ARTPOP at #21.

On Monday, we learned Lady Gaga’s station adds spiked on Pandora almost 1,400% (week over week). And more than 24k Pandora listeners added her station to their account on Sunday alone.

Apparently, her Vevo content saw a 431% lift in hourly views globally (when compared to her average hourly views in the last 28 days); in the U.S., there was a 1878% increase. The top viewed video was 2009's 'Bad Romance,' which generated 100k+ views in one hour (8pm ET). The second most-viewed video was 'Poker Face' with 68k views followed by 'Million Reasons' with 60k views.

As Tom Petty and the Heartbreakers did a few years ago, Lady Gaga followed the performance with the announcement of a tour that starts 8/1 in Vancouver, B.C. She has 16 shows in North America, including an 8/8 date at The Forum and an 8/28 show at Citi Field in New York, before heading to Europe. Tickets go on sale 2/13.
