An obituary for iTunes by Adam Clark Estes at Gizmodo:
It was swift and relatively painless. On June 30, 2015, iTunes gave birth to Apple Music, a much-awaited and disappointing pay-to-play streaming service. By this time, iTunes was in poor health, due to the viral popularity of streaming music services. Apple Music, I thought, would bring new life to the tired program. I was wrong.
At first, I welcomed Apple Music’s arrival to the world, realizing that it could make or break iTunes. I hoped iTunes would feel young again, fun again. But the opposite proved true. A few weeks after Apple Music was born, it was apparent that it couldn’t save the addled iTunes.
When you combine iTunes and the Music app on iOS, the situation is almost to the point of being untenable for me.
Does Apple decouple iTunes from Apple Music? Make separate apps for audio and video? I don’t know. All I know is on it’s current trajectory, iTunes (and Music app) is not working.
