More importantly though, Spotify doesn't directly link artists to bands they're in. For example, on Spotify, Billie Joe Armstrong is credited with his work on Green Day, but if you go to the Billie Joe Armstrong page, he isn't.

For example, you can see just the songs that Paul McCartney wrote (turns out he wrote a track for Drake called Champagne Poetry in 2021... who knew). On Paul McCartney's page on Spotify he isn't even attributed to The Beatles
