Not Philadelphia. He hasn't sold out in Pittsburgh yet. She sold 146,000 tickets in Pittsburgh. He's have a problem selling 18,000 (or whatever the arena will seat that night). And even with having nearly 130,000 more tickets in circulation her tickets sold for more, a lot more, on the secondary market than his tickets are.
I'm not saying all time, or over their whole careers, or anything like that. I am saying that right now, in 2023, she is more popular that he is. And it's not even close.
And by the way, you don't think she can sell out two shows in Barcelona. And yet the tour dates that she just announced, all stadiums, no arenas, includes three nights in Paris, two nights in Stockholm, Edinburgh, Liverpool, Dublin, Amsterdam, Zurich, Hamburg, Munich, Warsaw and Vienna, and a total of five nights in London at Wembley. That's to go along with SIX nights in LA at SoFi, plus the Latin American shows, inculding three nights in Mexico City, and two nights in Buenos Aries and Sao Paulo.
She is, by far, the most popular music act on the planet right now. Whomever is in second is not even close. And Springsteen almost certainly isn't in second.
