They don't all come formatted correctly, music can ripped in many formats which the car cant play no matter how tech simple you are, 199 songs is not a music collection, transferring ripped songs double rips them causing a loss of quality when played from the onboard drive, it takes more than 5 minutes just to take the elevator down to the garage for some people, some people cant play anything no matter what they do and neither can the techs in the dealership due to the car needing an update, some people cant play anything no matter what they do and neither can the techs in the dealership after updating, your lack of having an issue in this matter or any other has absolutely nothing to do with anyone else having an issue or not having an issue, audiophile means interested or enthusiastic about sound reproduction and does not refer to skill level in making an infotainment system playback music from a drive.
Any other questions?
