In hindsight, if any?

She snatched all of Born This Way's GRAMMYs soooooo-........

Gaga and Britney

No one tbh. Everyone was slaying in 2011 when 21 was smashing and it didn't seem to have an affect on anyone's career other than Adeles.

Well she blocked Preach Now from an AOTY nom, as she overshadowed Her as the bigger 20something previous major Grammy contending female singer-songwriter with hits and millions of copies sold.

None

Lady Gaga's

Did that era damage anything doe?

She snatch Rihanna grammy's..

Everyone managed to slay in their own lane in 2011, but if I had to pick someone it would be the girls who had the big outlandish personas as the GP craved a more natural and personal artist after Adele I guess?

Gaga's

to bad Rih already won a Grammy that night

I feel like this thread was made with Gaga in mind.

It's very rare that an artist ruins another's career, and 21 didn't really ruin anyone's.

We Found Slayage was released and that became one the biggest hits and Rih's biggest hit so far ...

So yea Adele didn't ruin anyone

Katy

Well it is made by SupahBass, so you're probably correct.
