2 things...

ALL stars are manufactured. Nothing goes from the womb to stardom. When you get into the major system you are refined until you are a perfect product. Might have a smash song but no image, might sing your ass off but no "story", might be an ok singer but have a star personality. All of the holes get filled in either by the label, a producer, a stylist, management etc.

with that said then.. most of the artists we never succeeded were probably manufactured in someway. Look at any labels books. They might have 1000 ppl signed and 4 blow up.

Women get the tag A LOT more because there is straight up more that goes into a woman's image than a male artist. Make-up, styling etc... Visually they will always be more manufactured
