But the iTunes Store back-end is a toxic hellstew of unreliability. Everything that touches the iTunes Store has a spotty record for me and almost every Mac owner I know.
And the iTunes app itself is the toxic hellstew. iTunes has an impossible combination of tasks on its plate that cannot be done well. iTunes is the definition of cruft and technical debt. It was an early version of iTunes that demonstrated the first software bugs to Grace Hopper in 1946.
Probably not coincidentally, some of iTunes’ least reliable features are reliant on the iTunes Store back-end, including Genius from forever ago, iTunes Match more recently, and now, Apple Music.
I feel like iTunes 13 has to be a re-do. Maybe I’m wrong, but Apple Music is such a bolted-on mess compared to the relatively well-done iOS versions that 12.x has to be a placeholder for a fairly ambitious rewrite.
