I didn't even do a list, girl.
I love Pink. I wouldn't deny that at all. And there have been way too many examples of Bey changing a chord or a melody in a demo, adding or taking away certain parts, videos of her actually writing and collaborating with other writers... It's just that you don't wanna give her credit where it's due. She's talked about Ring the Alarm and how she
loves the song because it's a blank canvas for her to make it sound however she wants it. She can make the bridge go high or low, she can add her own harmonies, she can sing it in whatever key she wants. She has videos saying that she
loves arranging songs and it's her favorite part of arranging. Even her former bandmates have said she excels in harmonizing and coming up with these crazy harmonies. You're being crazy and a troll now.

Yes, changing a demo...
It's called collaborating and adding input.
She has songs that have been started from scratch also, such as I Care, where she's come up with the lyrics, melody, and had a hand in the production.

Awww! You're so CUTE!
Beyoncé is definitely an artist.
You may not like her artistry, but that doesn't mean it's not there.
Her approach to music is like that of a scientist.
She blends so many unconventional elements in her music and it somehow works.
That's an artist.
You have a song like Ring The Alarm, which is basically a bunch of noise.
You have an urban bass, a drum pattern, an electronic noise, and an alarm.
With that, she created this aggressive, and angry song.
And the song is basically created by her voice because the instrumental is essentially bare.
The melody is created by her voice.
The harmonies and different levels of moods in the song are all created by her voice.
That, to me, is an artist.
There are plenty of examples I can give you following this same example.
I can break down each and every single song in her discography and find artistry in it.
