It's no secret that Lady Gaga is the most global superstar at the moment (if you're in doubt/denial, check the receipts thread + BTW Ball tour thread). What do you think it is about Gaga/her music/appeal that sets her apart from other artists that primarily have success in only a few select countries?
No shade
because she's on her moment right now and well she made an impact not only with her music, with tons of other stuff plus there's anyone bigger than her now.
