Thabks for that. I've not been paying attention - the major labels have all sold (almost all) their stakes over the last few years.

I can’t find any references for when the 3 major labels held significant stakes in Spotify. Only Sony did with 5.7% at the time they went public, according to the principal shareholders section:

Other majors had slightly less than Sony each - just under the 5% threshold.
