I only listen to hundreds of musicians and Spotify gives me those hundreds for $15/mo.
Those hundreds change by 10% ~ 30% every month into other hundreds.
I don't feel any ethical need to compensate musicians I don't listen to. And the ones I do listen to I don't feel strongly enough attached to to pay more than $15/mo for recurring access.
There are perhaps 10 whose permanent media I would buy and replay, if they left Spotify.
