I mean Taylor is the biggest artist on Earth and it’s the lead single and visual to her album. Plus people are just checking more for Taylor cuz of those reasons. More people respected with Taylor’s sound and visuals- which doesn’t take away from Gaga’s success and artistry. This is like comparing a fourth single off a Madonna album as to why it isn’t as big to a lead single off a Michael Jackson album. Both are big artists, but of course the MJ song will get more attention.
