In other words, your friends and your family is your audience. Be thankful they like your music. As far as spreading it further, good luck!
I’m not gonna listen to it. I don’t know you and I don’t trust you.
Your only hope is if your friends think you’re so good they want to tell their friends, not because you told them to, but because they want to. Because they think you’re good and their friends will like you. They can’t tell their friends to listen to crap, then they’ll burn their trust, and trust and credibility are key today, you don’t want to be kicked out of anybody’s movie, not if they’re important to you!
