I like how you think labels correctly label anything. I happen to work at a music streaming service (not Spotify) and I can definitely say that those datasets are insanely noisy and generally you can't really trust labels to, well, label their data correctly for anything.

I was about to say something similar. I don't even work at a streaming service, but I know label-provided metadata is enough of a steaming pile that there are third party start-ups which promise to help with the problem and such.

One track I bought on iTunes had credits for both "Bob Dylan" and "B. Dylan" on the same song, or something very similar like that.
