1> Fuck all of the above.
2> Choose a sensible subject.
The following subjects will be useful for makeing a real living in music.
-Business & Marketing
-Law (specialising in Contract Law)
-Electronic Engineering (specialising in audio applications)
-Computing (specialising in DSP coding)
-Hospitality and Events Management (cuz your name isn't Micheal Eavis).
-Graphic Design (Someone has to build those lovely Flash widgets that play your opus creations on your Myspace page)
-Printing (Someone has to print all you flyers & merchandise don't ya know..!??)
While you're studying a subject that gives you real skills, you can still learn to produce in your spare time and become the next big thing.
Ask yourself these simple questions.
1>Who makes all those lovely VSTs you crack? (People that can code).
2>Who designs and builds all those lovely rack units you wish you had the money to buy? (Electrical engineers)
3>Who do you turn to when you're offered your first label release contract? (A solicitor)
4> Want to start or work for a label? (Labels sell a product. Sales and purchasing experience and an understanding of both economics and business law are going to be very fecking useful.)
5>Want serious money for events? (Hospitality and events management courses will help get you up to speed on the legal and practical aspects of putting on events larger than a local club night.)
6> Want to be a live sound engineer? (Serious knowledge of electronics will get you further than the ability to use a mixer in the long run.)
7>How much money do you think the owners of music technology stores make? (More than I do haha

) (Solid business skills are needed to setup and run a successful store.)
Etc etc blah blah. No offence meant.

I know as much as many of you guys out there who have studied music tech at college. I learnt everything I know from reading books and mags + spending more hours than I care to calculate fucking about with kit....
