So you want a job in the music industry?
Whether it's as an audio engineer, a band, a rapper, a producer, a record label, talent management, A&R scout, whatever it may be, the rule is always the same; JUST DO IT.
The music industry is an extremely saturated industry full of hopefuls that dream of making it big, living as one of the rich and famous. But seriously, how many people do you think can live like that? You can certainly accomplish your goals, but it's going to take time and LOTS of hard work.
First of all, immerse yourself. Get involved as much as possible. Intern at places related to what you want to do. Keep in mind that you're probably going to fail a few times before you succeed. That's fine and normal, just don't give up.
Reach out to people and market yourself. You're not going to get anywhere if nobody has heard of you, so you need to get your name in peoples mouthes.
