As (limitações da) rádio e o (segredo do) iPod

«Years ago, radio had abandoned the idea of providing variety to listeners and instead concentrated on putting just a few well-tested songs on "heavy rotation" so the most popular tunes at the moment (generally the lowest artistic common denominator, catchy and forgettable stuff) would dominate the airwaves. Who could tolerate such unimaginative programming when there were iPods, which could shuffle thousands of songs that had passed the ultimate focus group - you, the sole listener, endorsing every cut because you consciously ripped it into the system?» (levy, 2006: 248)
