Spotify, Apple Music, et al are rent-seekers: digital music landlords over their vassals, big record companies. When recorded music became free as a result of file-sharing, these lords offered protection to the suits. Why pay _them_ for that which belongs to all humanity? Bread and roses, y'all.
Dump them as soon as you can (even if it means torrenting) and pay what you would have to the artists as directly as you can manage. Reject #technofeudalism.
