Another important thing that you need is a music marketing plan. Your marketing strategy can really make or break your music business. One thing that should be a part of your marketing strategy is to leverage influencers in the industry.
If you are able to get a great social media following, you are going to have a much larger base for you to market your music to. Social media influencers are incredibly helpful here, as much as you do not want to utilize this. You could also consider doing things like podcasts. People love podcasts and as a music business owner, this is a great way for you to take control of your music and the marketing of it.
This may not make you a lot of money on its own but it can raise awareness for your brand. At the end of the day, the amount of people that you have in your network is going to determine how successful you are.
