What Krukowski means by “the marginal-the rejected-the repressed-is whatever the powerful have decided is of no use at the moment.” is that the powerful decide what is important and what is not. He is trying to put significance on the marginalized. Music indicates the differences between the powerful and the marginalized because they both think of music in different ways. They could think of music as negatively or positively. The distinctions Krukowski makes between being surprised by music and discovering music is that you feel different from each. The differences he describes are that surprise is not that helpful and that discovering is based on what we like. The music listening experiences enabled by Forced Exposure are different from platforms like Spotify because there is an algorithm in Spotify. Spotify will show you music similar to what you often listen to because of the algorithm.
