Yes, there are different ways to subscribe. And again, I find it extremely weird to be supposed to keep paying indefinitely because you keep using something you bought.
It's because you value the artist, and want to support them continuing to make new things that you'll like in the future.
Rapidly changing economic structures can strip away sufficient economic reward via the ordinary way of 'purchasing' things, such that continuing to make them is no longer viable. E.g., Spotify paying artists $3.3 per one thousand streams, but almost no one buying CDs.
They are proposing ways — in this environment — to direct more of the funds directly to the creator, so that they can keep creating. But if continued creation is not of value to you, you are free to skip it.
