I think so!

I don't know. But I think not. Blackout was at 900K+ at the end of 2008 and it just hit the 1 Million mark this year

In 3+ years.

I don't know about this one.

You always make it seem worse than it already is.

It was at 732,000 at the end of 2011. It's at ~784,000 right now.

After some years maybe..

I don't think it will to be honest.

The album was at 735k last time we got sales for it in January. By now, it's passed 750k.

However, the problem is the album left on a low-note. Its last single was one of Britney's biggest flops, she came off her most unfavorably received era and the general public just wasn't feeling the material.

She will have to really come back HARD next time around for Femme Fatale to even get a small rise in sales because right now, she is not in the limelight and it's not looking good. The album may pass 800k in Nov/Dec, but it'll have an uphill battle from there.

I have to disagree. A lot of people LOVES Till The World Ends. It was an anthem in 2011. The problem about her albums since Blackout was the lack of promo. I really hope she'll be an X-Factor judge. It will help her a lot.

No.

'Criminal' did flop, but it's not as if it didn't make the Hot 100:

#4 Dance/Electronic Singles Sales
#19 Mainstream Top 40
#20 Hot Singles Sales
#21 Digital Songs
#55 Hot 100

I also disagree about the public not feeling the material. Billboard did a special called 'Britney's Biggest Billboard Hits' in honor of her birthday last December. Here's the top 10:

#10 Gimme More
#9 Oops!...I Did It Again
#8 Toxic
#7 I Wanna Go
#6 Hold It Against Me
#5 Circus
#4 Til The World Ends
#3 3
#2 Womanizer
#1 ...Baby One More Time

The lack of promo is the main problem. Unlike most teams, her team doesn't know how to promote her and her material without her actually promoting.

No

Maybe eventually. Very eventually.

"Criminal" was not one of her biggest flops. "Radar", "My Prerogative", 90% of the Britney era singles and "DLMBTLTK" did way worse. And the era is FAR from her most unfavorably received. I don't know what world you were living in.

The singles all did amazing for Britney and her state in the industry/for herself as an artist. First three singles went top ten, the first time that has ever happened for her. Another No. 1 single. ~6 million singles sold off of two televised performances. Grabbing her biggest radio hits, some of her best critical reviews for the album/singles.

Maybe.
