The iPod, like the Walkman cassette player before it, allows us to listen to our music wherever we want. Previously, recording technology had unlinked music from the concert hall, the café, and the saloon, but now music can always be carried with us. Michael Bull, who has written frequently about the impact of the Walkman and the iPod, points out that we often use devices to ‘aestheticize urban space.’ We carry our own soundtrack with us wherever we go, and the world around us is overlaid with our music. Our whole life becomes a movie, and we can alter the score for it over and over again: one minute it’s a tragedy, and the next it’s an action film. Energetic, dreamy, or ominous and dark: everyone has their own private movie going on in their heads, and no two are the same….Theodor Adorno… called this situation ‘accompanied solitude,’ a situation where we might be alone, but we have the ability via music to create the illusion that we are not.
