I'm not sure I understand what you mean by "certain date" but it is a subscription service, you can only play files for as long as you maintain the subscription.
FWIW, for me it changed everything. Well, you know, I'm still thinking about it, but... for a certain $ per year, I can buy a few dozen albums, or listen to hundreds. Sooner or later, streaming will be high res too.
There are some caveats - some labels don't allow streaming, and they don't have everything. If you have to have certain albums, maybe you won't find them. Otoh if you are looking to explore... at a listenable level.
I'm not selling it, altho I think perhaps I might.
