The flaw in your argument is assuming that the female jazz singer who weighed 300 pounds would be taken seriously enough to be given a change to record the album in the first place. The dude, IMHO, knows what he is talking about and his whole presentation in that video avoided logical blind alleys and unrealistic assumptions when he laid out his case.This speaker maybe highly educated, but he is seriously mixed up.
Record companies care about one thing and one thing only......UNITS SOLD.
If a female jazz singer who weighed 300 pounds and did not look like a fashion model
came out with a record...called..."the fat lady sings" and it sold 10 million units.
The "Fat lady sings volume two" would soon be on its way.
This dude needs to grow up.
