The summary makes the article sound a lot dumber than it really is. But it is dumb, and the core dumbness from which the rest of the article derives is here:
I thought about setting up a self-hosted media server to stream everything to my phone. But ultimately, I got lazy
He knew real the solution to all his problems, but like he says, "I got lazy," and so he went to his comical Plan B. Despite weird statements like this..
Many folks are sick of streaming in general. They’re sick of giant corporations, algorithmic playlists, and an internet infested with AI slop.
..he actually doesn't appear to have any problem with streaming at all. It's just that he had been using a proprietary streaming service called Spotify, which does things very differently than a user-oriented approach (e.g. self-hosted subsonic API server) would do. Navidrome isn't a giant corporation, the algorithm of its playlist is "play what the user told me to play" and whatever AI Slop you play depends completely on what AI Slop you decided to add to your collection.
But by conflating streaming tech with proprietary streaming services, he gets to make up a lot of non-existent problems with streaming and sneak by the core premise of his entire article: "I got lazy."
So he decided against the obvious, and instead, went with a less convenient alternative. I particularly liked the part where he called cassettes "compact and super-portable" by comparing them to vinyl, instead of the actual media competition: flash memory, remote spinning-rust, etc.
