It’s actually even MORE weighted in favor of major label artists like Lady Gaga, thanks to special deals between the big majors and Spotify. My numbers aren’t exact here, but this is the principle of the deal - let’s say Lady Gaga gets 2% of streams and random indie artist gets 2% of streams - because of the deals, Lady Gaga’s music gets paid out 2.5% of the pot and the indie gets 1.5% of it.
If a rando artist suddenly gets as many streams as Gaga, then Spotify might make that deal with the "random indie artist".
But let's be real - majority of people go to Spotify BECAUSE there is Gaga, Beyonce, Taylor Swift, Rihanna, Adelle, The Weekend, Shawn Mendes, etc... If you take those names out of the pot - Spotify turns into crappier Soundcloud.
These indie artists literally cottail on the big names.
