I think she's just lucky because not many big artists are releasing. I mean no britney, no Rihanna, no Gaga, no Miley, no pink, no Katy, no JT, no Bruno, no Adam, no Adele, no Eminem, ...
If there were more competitions, I think 1989 would never perform better than her previous albums.
Dead @ you thinking any of those would be competition to her. The reason why there is no competition is that they are avoiding releasing around the time Taylor releases.
Adele, Britney, Gaga, Beyonce and Katy could've all released in the same year as 1989 and it still would have slayed. Its quality pop music that both the fans and the GP enjoy and she is a very likeable person.
1989 is better than ARTPOP, Britney Jean, Prism, 21 and 20/20 combined.
