Both are huge especially in the US but who is bigger WW?

A tie

Katy

Taylor. She is in the global trinity Adele - Gaga - Taylor now.
Katy has never been that global on the first place.

Katy.

I think I'm going to have to go with Katy Perry!

It's quite an obvious answer if even Taylor is singing Katy's songs!

Katy

n yea Gaga isn't in it anymore

i'm gonna have to go with mother perry! sister little legend!

Only a truly global act would have other high profile musicians being impacted by their songs

Katy.

@Kats i couldn't find Katy's recipts care to compare?

Katy easily. She's bigger in South America, Europe, Africa and Australia.

Taylor is actually only big in North America and couple of Asian markets.

Didn't Taylor only tour like 10 dates outside America? Gonna have to go with Mother Katy!

Sorry if that isn't the answer you were trying to get with this thread, little monster

OT: Katy but both are global!
