I think the music industry is one facet of a many faceted pyramid of tripartite ecological conditions so precise that they are borderline suspicious of conspiracy.
Work, sex, and family figure, are the rough three base motives for all particular ethical and moral agendas and behavior. Everything is oriented around them.
To express these there must be a medium. These mediums are such things as music, drama, athletics, sexual prowess, masculinity/feminism, and career.
For the adolescents, the major expression is sexual and gender related, achieving masculinity/femininity, is the occupying motive in the first eighteen or so years.
Most if not all of the sexual identity, as well as the amplitude of individuality and independence- the rebellious and declarative spirit of a teenager who dares to break rules and cross limits- is passed through the art industries and clothing industries.
A kid, nowadays, does not beg Repunzal to let down her hair, or beckon to Juliet. He just buys some clothes and listens to some music…to sign-on to an indenity described in the lyrics of the songs, themes of the sit-coms, styles of the clothing, shape of the body, hair, etc. Listening to certain kind of music says alot about one sexually as well.
Marlyn Manson is a lucky prostitute who gets paid well to prepare, for greedy corporate vocation, the way for commercialism to boom through product sales in the fabrication of identites. Manson is your basic:
“middle-class white kid being scrutinized by other races, his parents, authority figures in general, an indifferent God, his unfaithful trailer-park girlfriend named “Rhonda,” a low wage job washing dishes, pressure to decide about college, and otherwise hostile and discomforting events that, coupled with the end of puberty and a few scars from radical skate-boarding, make one a restless person who wants to wear black clothing and go to Star-Trek conventions after hanging out at the comic book store Friday’s with gothic friends, and that girl from school who wears the ice-blue contacts and spiked dog-collar”
…type of persona generated from that specific angle of music and theme. The identity is created and behavior norms are established in conduct…kids act like their favorite rock-stars or rap-stars or movie-stars, etc.
The teen age years are the most malleable and music style is one of the strongest influences on personality when constructing an identity of beliefs and behaviors.
