Fair. I was exaggerating a little.
My point is this: I spend over 100,000 minutes per year listening to music. Any unnecessary friction in the experience is therefore extremely frustrating and has a disproportionate effect on my life. In all my experience self-hosting, it adds a certain level of friction that just isn't worth it considering how much time I spend listening.
I am not hostile to self-hosting in other cases. I am very satisfied with my self-hosted Plex server, for example. But I don't spend 30% of my waking hours watching TV.
