How can I change the genre of the song I am promoting? How do I ensure that the release makes it to the right genre of curator, and edit the targeting?

To change the genre of the track you are promoting, head to the "Track Features" section of your track's Marketplace page:

We suggest only tagging the most relevant broad genre, because the system mostly relies on other metrics like playlistability, playlister’s previous interactions, and more, to accurately tag your music.
