Popular entertainment is not musicology or anthropology. It's four function math. Count the audience legs and divide by two.

Adele has taken home something like 15:18 Grammy nominations against similarly marketed & packaged & talented dentist office Muzakettes. Pretty good average for her league.

When I hear pro sound engineers in American pop say 'natural' & 'authentic' I reference the absence of vocal processing like Auto-Tune &c. The accents never really come up in conversation. Scots excepted of course.
