A music colossus already tried this, and Tidal landed with a thud.
People are loyal to artists, not labels, and artists change labels on a fairly regular basis. It's not like TV where shows generally live and die on a single channel, and maybe get salvaged onto a second one.
And if not loyal to an artist it is a genera or station. Classical music listeners can get Bach from a number of different artists, if a few are missing they typically can get by with the others. If someone puts a station on Pandora it will be a long time before they notice that something is missing.
With TV there is a long standing character development to get people interested in something in particular. With music you often just want a style - though there are favorites with particular meaning that you may want.
Even loyalty to an artist is overrated. Tidal had exclusivity with some of the biggest names in music with dedicated fanbases and this mostly got people to sign up for the one-month free trial and cancel.
Beyonce and Jay-Z moved back onto Spotify. This is a model that is proven not to work.
To be fair, there is also a difference between streaming shows and music.
For shows, I sit on my couch and either open Netflix or Prime Video, and then start the show I'm going to be watching the next hour.
For music, I have Spotify playlists for different moods/genres. If a specific song/artist is not on Spotify, too bad, but I'm not going to stop cooking, wash my hands, go to my phone to switch apps, go back to cooking, stop again in 10 mins. to go back to Spotify
