I am currently a business major with a concentration in marketing. I used to think that it was vital for me to study music management to become a TM/manager but after talking to various people in the industry I know now that is so far from the truth! I know of a successful TM who majored in english! It really is all about real world experience and networking. I think the best way to do that is with internships! Major in something basic, that you don't despise, and fill in the gaps with work!
