Lots of the reasons why I still listen to CDs have been mentioned here before.
The same goes for the argument that with buying physical media artists actually get paid. It bugs me that with streaming the people paying (so to speak) for my convenience are the artists. They generally earn a pittance and money goes to the owners and stockholders of streaming companies. Spotify’s Daniel Ek is quite outspoken about the fact, that musicians are just content providers to him (which keep the business running that makes him even more rich.) Most of the artists I like have low streaming numbers. There is a lot of music that people used to happily buy in significant numbers, music that they only play from time to time, music that does not go into heavy rotation anywhere. In physical media times you could still survive like that, with streaming not. On top the popularity of streaming and the way it works (popular playlists, suggestion of similar music etc) brings about a certain blandness. It‘s tougher than before to do something new and daring and make a living from it. It‘s literally calculated what many people listen to (and what they watch). It‘s a bigger discussion but I feel this all need to be pointed out because there‘s not only our consumer side to consider. Having said that, I do stream from time to time, mostly to listen to newly released songs or stuff I don‘t know. Then I gladly buy the CD.
