I've heard about this before too. Definitely not the greatest for artists. However, most decades have had their ways for people to get music for cheap, and they usually mean that artists don't get paid very well. Think cassette recording off the radio back in the 80s and 90s. Artists typically make the most money off of touring and merch. Which, again, sucks, but I don't think Spotify is doing much more damage than artists experienced in any decade. They also encourage people to listen to up-and-coming artists, discover new music, and break out of your normal tastes.
