Aside from her hairstyle.

N/A

She makes good music, thats one of them for me.

But she has started a trend on radios.
When your songs are generic and repetitive, of course it's gonna sound like the rest of pop radio.

She has plenty of wannabes trying to recreate her persona, for starter

You're making it sound like her discography relies heavily on Rih's input.

atrl and its obsession with 'impact'

Oh. It's easy to emulate a basic radio artist.

Most streamed female on Spotify/Youtube and best selling digital artist of all time speaks for itself

Not everyone has that

A lot of the Navy claims Rih has a big cultural impact.
A lot of Navy discredit other pop girls' success due to their lack of impact.

People like to dress like her.

Doesn't exist.

She's one of the key players in popularising the dancehall/tropical pop trend that's literally everywhere rn.

Doesn't she have a gigantic cardboard cut out of her in a bikini. lol I mean she was just at the beach and the next thing you know there is a larger than life cut out of her ...

Lol.
Culturally important, indeed.

Im so sorry, but I really do like Anti. I'll leave.

Success = Impact.

As mentioned by some Navy.

She doesn't have any. She's your generic pop artist. Another will come along to replace her in a few years.

She inspired a song by The Wanted.
