Music streaming is not currently suffering the same fragmentation that video streaming displays. I.e. the same music albums are available on all those music streaming services you mentioned. (I know there are a few exceptions but for the vast majority this is true).

Music streaming services have very few exclusive content. Which is why they tried to sign exclusive deals with e.g. podcasters.

Should they go in the same direction as video streaming, we will see an increase in music pirating again as well.

Hasn't stopped Spotify and co from increasing prices anyway of course.
