Mabelle, you've picked possibly the worst time in the world to try and get a job in the music industry - most companies are making financial losses and theres cutbacks happening everywhere. (As it happens, I'm also looking for a job in the music industry, so I know how it feels!)
Having said all that, getting a job in the music industry is alot more about WHO you know than what you know. A degree won't put you above someone who hasn't got a degree, if they make friends with the right people they'll get the jobs, as industry folks tend to employ people they like and give them a chance rather than someone with an impressive CV/education. Plus, most of the jobs in the industry don't require a degree just a bit of common & business sense, and a love for music.
They also rarely advertise jobs (see above about how they give jobs to the people they like), and if they do, they advertise in the specialist industry press (ie: Music Week).
Best way to get your foot in the door - go to as many gigs as possible, signed and unsigned bands, bands that you've never heard of, stuff that you don't even like. Just go. Spot the people that also are at every single gig. Even if they only hang about for a short time. Talk to them. They'll be the industry folk - booking agents, A&R people, managers, publishers, journalists, promoters etc. Talk to the guys that run the venues, they'll know who to speak to and they can point them out to you.
Just befriend them. Most of them are a nice enough bunch and quite a few will be more than willing to help you out in finding a job.
I'm not saying they'll give you a job, as not everyone is in a position to hire people, but they can tip you off on jobs that are coming up before everyone hears about them, introduce you to the right people, teach you a bit about how the industry works, put in a good word for you to prospective employers etc etc.
I dunno about the US, but over here theres a few temp agencies that deal with just the music industry. It's often worth joining one to get some experience and think about if you really want to work in the music industry. Also, just phoning companies to ask if they have any work experience placements going. You won't get paid, but you will learn a huge amount and meet the right people and if you make a good enough impression they might even take you on full time.
Hope some of that helps in some way and that you get something soon!
