“Listening to music on your iPod is not about the sound quality of the music, and it’s more than the convenience of listening to music on the move. It’s that so many people are doing it, and you are in the middle of all this, and all of that colors your perception. All that sizzle is a cultural artifact and a tie that binds us. It’s mostly invisible to us but it is something future generations looking back might find curious because these preferences won’t be obvious to them.”
