My last experience with iTunes was a long long time ago, in the iPod days, when you needed to use it to sync music, but it was a horrible piece of software back then.
It’s more horrible now. Syncing now opens a Finder window with an inconsistent look and feel, and sometimes fails to copy new songs in a synced playlist. The playlist view has the album art taking up half the screen, but there’s no way to shrink that section. And there’s no visual indication for whether shuffle is on - it has no grey box around it when enabled.
I kind of think they made it shitty on purpose to push everyone towards a subscription. Many of these issues apply to locally stored songs and playlists, which is how I use it.
Did you use it on Windows? I never understood the hate for iTunes. It was a dream for someone like me who'd spend hours customizing their library. A far cry from today's software from Apple.
In fact, I was never able to use Apple Music because it handled bad internet atrociously. And last time I checked (2022?) it was still not fixed.
It's a meme created by idiots who for some reason wanted to shit on Apple. Hilariously now the same memers will defend Apple tooth and nails even though Apple has never been so bad at software.
iTunes was a great software, even people using it on Windows liked it a lot.
