No, the problem is the record labels. They are the ones that hinder artist revenue from services such as spotify.

I don't consider pirating and yes, if spotify (and all similar services) were shut down and I were forced to buy albums on CDs the artists would get much less money from me.

Also remember that the day I end my spotify subscription I have nothing to show for it. I've spend many hundreds of dollars on spotify and the day I stop paying I will not have a single track to show for it.

How many people actually constantly buys music every month? A monthly spotify subscription isn't much per month but it adds up.
