No, simply uploading your music to Spotify does not guarantee that it will be promoted or featured on the platform. Spotify uses algorithms and human curators to determine which songs and artists to promote and feature on its various playlists and other promotional channels. To increase the chances of your music being promoted, you should focus on building a strong fan base and promoting your music through social media and other channels. You can also consider hiring a music promotion agency or a publicist to help you get your music in front of more people.
