That was my thought too Phil,
And it sounds like Delight Tunes meant the Christian church too, which is really a fairly new thing at 2,000 years, while the Jewish church goes back 4 or 5,000 years I think... admitttedly they are big on music too!
But people have been blowing through old animal bones and trying to fart in harmony for millions of years.
Clearly the notion that music 'started' anywhere or at any time is floored and just a tiny bit egocentric.
On the other hand, if it meant that much modern pop music has been driven and inspired by gospel etc, it is dead right.
Speaking as an atheist I think it is all a load of hogwash, but still very pleasant to listen to.
