To be more generous, there are also many cases where more obscure music will start evaporating from your playlists. Some of us have serious problems with this kind of UX.
This is why I personally built a home media server. Lapsing licensing agreements, older content, escalating streaming subscription costs, etc all led me to it. The secondary effect of being able to consume the content without depending on anything other than electricity is an additional benefit.
This is something else I forgot to mention, but it drives me absolutely mental. Music vanishing from my playlists, old TV shows I'm watching are suddenly not available. Paying for that kind of experience strikes me as a horrid proposition.
