With her highly-anticipated third album 25 due out this November, will the true elusive chanteuse Adele beat Britney Spears' long-standing record for the highest US album sales week by a female artist?

Definitely not. At most I see Adele doing 700k first week because of the long break. But we'll see.

Depends on the level of promo

Anything Could Happen, boy.

She can easily debut with 1M+ at least. She actually has a decent chance.

Now that streaming's included with the BB200, Adele, and Taylor's next album will more than likely do it.

Promo and Hype are huge.... She will do 1,8 Million

Depends on the promo, lead single, etc.

I don't think she will.

No.

If she goes all out with her promotional campaign and delivers a quality lead single, I don't see why not.

Nope
I expect around 600k first week.Adele's has longevity or at least she used to.

I don't think she'll do it with PURE sales. With streaming she probably will, though.

If JT did 900k. Lady Gaga did 800k+ Taylor Swift did 1M 3 times

Why wouldn't Adele ? Idk

She doesn't have that hardcore fanbase like Gaga and TS, but neither does JT.

If Taylor couldn't, neither can Adele.
