To illustrate why Apple Music is not at all suitable (I can think of some more graphical expressions) for classical music, let me give some real use cases:
1. I just took a seven-hour flight. I wanted to download something to listen to. As J.S.Bach’s polyphonic organ works are always akin a sudoku, I thought this would be a great opportunity to have some time to concentrate on them. I have two different boxes of CDs (around 12 discs) in my shelf but finding the music in Apple Music is not easy. Should I search for “Bach Orgelwerke”? “Bach organ works”? Finally I managed to find Ton Koopman’s recordings for Vol. 6&7 and Vol. 8&9. Nothing wrong with them, as Mr. Koopman is an excellent baroque keyboard player, but Bach’s organ works have been recorded many, many times by different artists. Where were discs 1 to 5?
2. Often, I need to find a specific work by its catalogue number. Almost all classical composers have these numbers, e.g., Bach’s famous Toccata and Fugue in d minor is BWV 565 (and probably not composed by J. S. Bach, but that is another story). Usually, I end up looking for music in YouTube because either the works are not available in Apple Music or the stupid app just does not find it.
3. I would like to find something new. For example, I’d like to find 17th century Italian violin music. A trivial search within a small set of metadata (year of composition, country, instrument). Nothing like this is possible with Apple Music.
4. Sometimes, I want to compare performances of the same work by different ensembles, orchestras, or conductors. Is there a difference how Verdi’s Requiem was performed half a century ago and how it is performed today? Again, very difficult.
I’ve come to the conclusion that Apple Music is lacking three things: music (most discs in my own collection do not exist), metadata, and search front end.
