There are several ways to promote your music on Spotify playlists:
Submit to Spotify's editorial playlists: Spotify has a team of editors who curate playlists for different genres and moods. You can submit your music to these playlists through Spotify for Artists or your label representative. While it is a competitive process, getting featured on a Spotify editorial playlist can bring your music to a wider audience.
Build your own playlists: Create your own playlists on Spotify and share them on social media platforms like Twitter, Instagram, and Facebook. Make sure to include your own music in these playlists and add other artists in your genre. This can help you gain more followers on Spotify.
Collaborate with other artists: Collaborate with other artists in your genre and create a playlist together. This can help you both reach new audiences and gain more followers on Spotify.
Promote on social media: Use social media platforms like Twitter, Instagram, and Facebook to promote your music and your Spotify profile. Share your Spotify links and playlists with your followers and encourage them to follow you on Spotify.
Reach out to music bloggers and influencers: Reach out to music bloggers and influencers in your genre and ask them to feature your music.
