The thing about her MVs not getting those views is because they are not that good,
WANEGBT was a smash but that video is pretty bad. Good concept, bad execution and production.
IKYWT was a pretty good video, but that long intro talk should've been shorter.
22 video was phenomenal. Sadly, the song flopped so no one really cpchecked out the video.
Mine was a great video but we all know the song underperformed. Back To December flopped. Mean was a country-hit only, STOF, no one wants to get into there.
YBWM had a phenomenal video, as well as being a huge smash. That contrubuted a lot to its views.
So basically, the stars are just really aren't aligning on the fact the a huge Taylor song smashes with a great video like the other popgirls, hence the low youtube views.
But they already aligned. SIO is smashing in views

Yes, her website confirmed that she will "kick off The 1989 World Tour with two shows in Tokyo, Japan on May 5 and 6, 2015"
There's like 10 days between her next show in the US, so she will probably have 5~6 shows more in Asia? That's too little though. I hope she will have a second Asia leg in 2016
Her website also said "1989 World Tour kicking off on May 20th in Bossier City" before the Japan shows were announced. I think she could announce more tour dates in Asia and those dates would be before Japan.
