They say that iTunes revolutionized the music industry. Indeed it might have, but at a price.
Before iTunes, record labels catered to the general audience; they still do. The lowest common denominator. They find and distribute the music that a general audience likes. by doing that, they alianate all those who like niche genres. iTunes did it differently.
iTunes purchased and offered everything. They catered to the general audience and to all niches as well; from the infamous to the unkown independent. iTunes even took everything CD Baby has to offer —and CD Baby is exclusively on online music store for independent artists (They also revolutionized the music industry, before iTunes).
iTunes’s distribution channel? The iPod. And now every person —armed with an iPod/iPhone and with an endless supply of his favorite genre of music— can indefinetly distract herself from her own thoughts; from the thoughts that matter, from the thoughts that resolve internal conflicts, from the thoughts that solve problems, and maybe from the thoughts that create and innovate. Before iTunes, the general audience lived distracted from reality, while the niche audience enjoyed its individuality. Post iTunes, everyone lives distracted from reality.
Maybe, for one day, you can forget your headset at home (à la Zoozel), and experience the difference.
