Same feeling here. I recently tried to switch to Apple Music because of the major new releases missing on Spotify. As someone who usually streams on desktop, the iTunes interface is really poor in comparison to Spotify for streaming. It’s clear the iTunes wasn’t designed for streaming, and Apple Music was just tacked-on to the older software.
I do wish that Spotify would consider caving to artists that would allow their music to be available only to premium subscribers. I guess ad-supported streaming is still a big piece of their business.
