i think Krukowski means that music is no longer appreciated through CDs. With the new technology in this world everything is so advanced CDs aren’t used anymore. People now listen to music through apps on their phone. The distinction between being surprised by music vs discovering music is when you’re surprised you have no expectations you’re just surprised of the unknown. Vs when you discover something you are looking for it. It’s important because this is how we understand music more. Forced exposure vs listening to music on Spotify is different. When listening to Forced exposure you can listen to lots of music but have to wait to make contact with the artist. Meanwhile with Spotify it provides music based on your interests or mood. Spotify has unlimited amounts of music.
