One of the only reasons for this is hipsters trying to connect with a past that they didn’t participate in. Trucker hats also sell well to that crowd. I use both Spotify and Amazon Music, but I buy used CDs because they still sound better than streaming and vinyl (I don’t have $1000+ to blow on a turntable and cartridge and needle that allow the quality to come close to CD quality). Now and then I will buy a CD based on new songs I’ve heard on Spotify. The vinyl craze will die off within the next 3-5 years, my guess. These same folks also think cassette tapes are the bomb. They will outgrow their hipster ways sooner or later.
