White people are underrepresented in the American music industry?

Just out of curiosity I decided to google the top 40 at the moment in the US and figure out what percentage of artists/groups are black, white or other.

My findings (Only band/artist names are noted -- not the songs they are on the top 40 with):

Justin Bieber - white
21 Pilots - white and white
Adele - white
Flo Rida - black
The Chainsmokers with Rozes - white and white
Selena Gomez - hispanic
Drake - black
Alessia Cara - white
Shawn Mendes - white
G-eazy and Bebe Rexha - white and white
The Weeknd - black
Meghan Trainor and John Legend - white and black
Bryson Tiller - black
Post Malone - white
Future - black
Daya - asian

Note: Please forgive if I wrote the wrong ethnicity for a certain band or artist, I only googled it so I'm sure it's not completely correct. Also member of bands were counted as individual artists, for example 21 Pilots is a group but both members are white so I counted both of them as white individually. I do realise that there are one or two English artists in the list but I am using figures on population from a 2010 US census just to keep from complicating things.

So in conclusion:
10 out of 20 white = 50% 8 out of 20 black = 40% 2 out of 20 other = 10%

Bearing in mind that the US is approximately 13% black and 72% white, and therefore 15% other, is it then fair to conclude that black people are over-represented and white people underrepresented in the American music industry?

What?

If you make good/popular music, you get into the top 40.

I don't get where ethnicity plays a role in this?

Only blacks can be underrepresented. Other ethnic groups don't count.

Why do you assume the top 40 singles is representative of the music industry as a whole? Have you done it for the Billboard 200? You'll find one white man massively over represented there: David Bowie.

What about backing musicians? Sound engineers? PR?

Even if black people are over represented,I don't see it as a problem. It just happens that music of black origin is very popular with the majority of music consumers.

In your opinion*

In the opinion of race-baiting pseudo-liberals.

I dont get why drake and the weeknd etc... get classed as black when they are litterally half white half black.

I just took the first 20 artists I could find who had their ethnicity advertised on the internet. If I wasn't sure, I skipped them.

Because it's america, and they think that everything with a shred of melanin is black.

I bet they class indians as black...

Nah. They are just classed as terrorists there.

Nah. They are just classed as terrorists there.
