Keep thinking outside of the box my friend, there are tons of way to make money using not just your music. You seriously need to start working on your brand as well, you aren't just some beat maker! You own a beat selling "BUSINESS". Here are a few things that my company does:
1. We sell T-shirts/Hats (Backpacks, Speakers, Headphones, Jackets, etc coming soon)
2. We sell promotions (Must have enough traffic coming in to do so)
3. We have song contests ($10+ fee to enter and the winner gets a payout)
4. We sell to other producers (making them beat pages to sell their beats on our site)
We have about 10 streams of income total and have only been in business 1 year (by we I mean me). I started selling beats online when I was 20, created Trizzy Tre Beats last year and have worked with artists from all over the world. It's not impossible my friend, you just have to do your homework and apply things from other business to yours.
