Guys, you need to chill.
Katy Perry is the most global female artist currently.
One Direction is the most global band currently.
Eminem is the most global male artist currently.
Even if he is a dark horse in ATRL, Bruno Mars has managed to slay with his first two albums everywhere
Wait for his third album coming out next year, he just said that he will be back to the studio once he finishes the tour which has already surpassed the 100m mark WW.
Shakira is global but she doesn't sell in US. But I have to choose so I choose Rihanna who is a very good seller in US, UK, France... And there is artists like Bey, Lady Gaga, Katy... That are global one era and the other they're not anymore. This is just like that
