She isn't having a downfall, she is Lady Gaga and she is known by everyone, everywhere.
What downfall
she is just not at her peak anymore and on top of that it looks like she doesn't even want to be POP (the same way she used to) anymore.
Same with Beyonce. I don't get it, why doesn't anyone say she is having a downfall, when her sales have declined as bad as Gaga's. OK not as bad, but the only reason for that is that her peak was smaller.
Yeah I know Bey is everywhere on the media and I am not saying she is having a downfall, but Gaga, despite declining a lot, is still Lady Gaga
She's already an established artist and her name is one of the most recognizable names in POP music period.
