She's completely manufactured, but the Swedish nerds on her hit-song assembly line know what they are doing.
The music industry has pretty much monopolized itself. Hire professional musicians to write music, professional choreographers to make a dance, and a pretty face that you can digitally alter her voice and you win. They'll take that pretty face, pay off radio, tv, whatever else to brainwash the masses by constantly saying stuff like, "we play only the best hits of today!". The sheep then believe it's the best.. cool and hip.. whatever.
For the most part, mainstream music is more about making corporate money than art.
It's like owning a cage-fighting business. (hypothetical situation) Don't allow the good fighters in.. publicize these bad fighters that you are promoting. Let those bad fighters fight amongst each other. You have ownership on both of them so it doesn't matter which wins. (although you could psychologically make one more appealing to people to keep tension and interest and drama..) The business makes money no matter how bad the fighters where because in this theoretical situation, the fans have never seen a real fighter before nor care to find one.
