Anecdote that is tangentially related...<p>We upgraded my wife to iPhone 6. When we&#x27;re driving around, she likes to listen to music on YouTube (don&#x27;t ask). So we plugged in the charge&#x2F;data cord to the car&#x27;s USB port. The phone charged, and the car&#x27;s system display said &#x27;reading files&#x27;, but no audio would play. Instead, after &#x27;reading files&#x27; it displayed, &#x27;no song&#x27;.<p>We tried a variety of different approaches, including playing YouTube on my iPhone 6 and plugging it in to the car. It worked. My daughter&#x27;s iPhone 6 worked. My wife&#x27;s would not.<p>So I made an appointment at the Genius Bar. We told the story. Their conclusion was &#x27;bad USB chip&#x27; in the iPhone and they replaced it as a warranty issue.<p>We took the new iPhone out to the car, and my wife excitedly plugged it in...<p>No luck.<p>Finally, I looked at the phone again and launched iTunes, which, of course, was empty. She does not have a music collection. Then the coin dropped... &#x27;no song&#x27;. You don&#x27;t suppose.....<p>Yes. In order to get any other media to play through the USB from her phone, she had to have at least <i>one</i> song in iTunes. I loaded &#x27;Year of the Cat&#x27; and sure enough, YouTube now played.<p>I am reminded of that anecdote because some time later, &#x27;Year of the Cat&#x27; was mysteriously deleted.
