All of the top gurls at the moment are frequent releasers: Rihanna, Katy, Taylor, Gaga, Beyonce
(The only exception is Adele, but we don't know how her next era will go yet)
I don't know why the other girls don't follow and increase their frequency
No not this.
Momentum can be in your 40"s and 50's even. Like madonna had momentum after confessions era.
I'm talking the commercial peak of an artist which is during their youth.
Guys stop co signing everything just to criticize yall sistrens.
The artists that were big before Gaga who released albums after Gaga with the same **** all declined. Gaga made people want that kind of artist. She fast forwarded pop music to what it is now and if people aren't with the program (even herself) then they flop.
. But she's gonna do her thang, I guess
