I have seen the least popular rappers come close to 100k. 1 million is not too far fetch for Drake. He is the biggest rapper rn.
Bey is going to alienate a big part of buying public with Lemonade. They won't be here for her this era. I think she will be selling less than 400k tbh.
I want both Bey and Drake to hit #1! I hope they release separate weeks. And like someone above said, the only people pulling higher numbers than that are Taylor and Adele. Amazing sales, and I do think she'll do more.
