Hey @dúanaylex,
There’s no formal submission process for Spotify playlists. Spotify’s curation team’s independence is an important part of what makes Spotify such a great listening experience for fans.
The curation team uses a combination of taste, data, research, and trends to create playlists for our users. So the best way to be considered for Spotify playlists is to make your music as visible as possible and maintain an active presence on Spotify. If your music is breaking, they’ll find it.
