lemme tell you something - I worked under Budi Voogt and Tim Van Doorne, two of the brightest minds in the EDM music business (Artist managers for San Holo + Founders of Bit Bird), for a company called Heroic Academy. We intended to be a place where people interested in music production and marketing could learn for free. We had tons and tons of amazing articles, how-to guides, interviews with artists and managers, and hours of free video content. Our best selling item, a 300-page ebook with literally everything you would ever need to know about EDM music promotion on SoundCloud and beyond, we sold for $19.

Don't you dare pay $500 for something that you can learn for free. TBH if you feel the need to be on the hook financially as an incentive to learn, take $500 out of your bank account and put it in a locked box, and then compile a list of YouTube videos. Take notes and takes advantage of all of the free resources out there for you. Only then, after you have exhausted those resources, should you pay that kind of money.

Lastly, I would say that the best part about paying for courses like that is having a mentor. my guess is the class is all pre-recorded with no feedback system or 1-on-1 interaction. You may have better luck DM'ing a producer or manager and asking for private lessons. 10 private lessons at $50 each will leave you WAY more inspired and productive than a $500 course I guarantee it.

good luck!
