This isn't a new argument. John Philip Sousa said phonographs would do the same thing. For that reason, he allowed his band to record, but he wouldn't conduct them (some recordings identify Sousa as the conductor, but that's a lie). I think he was right. My first car didn't have a radio, and I taught myself to yodel while driving to work. My second car had a radio, and I stopped singing and yodeling in my car. For that last fifteen years, I've been a cop, and I can't have the AM/FM radio on in the car, because it tends to drown out the police radio, so I've gotten back to singing to entertain myself. My voice has improved quite a bit, and I figured out how to do that throat singing (producing two notes at once, there's a previous thread on Mudcat about it). I don't advocate ditching music appliances, but there's nothing wrong with turning them off once in a while.
