Your parents were right. It is worth noting there can be a big difference between the music and the antics of the “artist”, most of which is more about marketing than anything.
Take a look at any group of people and there will be some whose lives are a total mess. The entertainment industry just uses that to get your attention.
On the other hand, some like Katy Perry or Taylor Swift infuse everything they do with sluttiness and narcissism.
Most people are interested in the music, not the lifestyle. Urban ferals are customers for sluttiness and narcissism, the music is just a soundtrack.
