As a male singer/songwriter I can tell you that women songwriters tend to, for unknown reasons, write their songs around female vocal capabilities, which are objectively higher than men's in terms of range and fluidity.
Women cover male songwriters frequently, but who are the great female songwriters? Joni Mitchell, Billie Holiday, Kate Bush, and so on. They all tend to be excellent vocalists who write stuff that the average man simply can't match. While the great male songwriters are often weak to average singers: Bob Dylan, Leonard Cohen, Lennon/McCartney. Women kill on those songs, with barely an effort sometimes.
As for modern Top40. It sucks. Who cares?
Although, Maxwell’s cover of This Woman’s Work is outstanding.
Actually you could hang around overcrowded charging stations and make some good money. People in a hurry would pay a premium.
