It doesn't take much to debut at #1 right now b/c of how low digital sales have fallen. Taylor shouldn't have any issue. Even if she only opens with like 400k (which would be quite a dip from the 620k the previous lead opened with, and less than "Problem"), she'll still easily get #1. Rude/SWM are selling like 110k/week.
Rude was #1 last week with like 500 points total (including airplay and streaming). I have no doubt she'll easily surpass that, possibly in sales alone.
Her competition is the weakest it could possibly be right now.
Twigs is similar to Lana (BTD era) in the way that even though they're new and probably don't have a very large budget, they both put out amazing videos and have a very distinct image and sound.
Lana was on Interscope and had several big budget videos. Stop trying to make this comparison happen.
