It's your music that created right? We never want to spam ppl but we do want them to follow you and add your music to their playlist. The only way to build a loyal fan base is to be a consistent marketer of yourself and demand the follow from ppl. When I talk to some of my fans and they ask me where do they find my music I tell them spotify but what I also do is ask them to pull out their phone right there and follow me or when I am performing I tell the audience all at once. No matter what never stop promoting yourself and find creativ ways to drive traffic to your artist page on Spotify.
