In the way of hearing episode 5, Damon Krukowski illustrates how the development of the music industry has changed. Music is available everywhere nowadays but back then people used to get CDs and other related music from record shops. Apps like Spotify and Soundcloud have made it easier for people to listen to music and some suggestions that people might like. What I also think  Krukowski is trying to say is how the big companies have power over us and our interests, when they use algorithms, which collects personal data. Companies get the advantage of us by collecting these data and give us more suggestions that can be close to the kind of music we might like. After all, he pointed out how beautiful the record shops were and how they were full of information and knowledge about songs and artists. Entering it feels like entering a different world without the need of taking your personal information.
