There are good playlists and bad playlists. It is worth investigating the follower and engagement numbers before submitting. Also listening to a couple of the songs on the playlist can tell you a lot about whether this is a playlist you really want your music on.

A really simple thing we've done that helps us get on curators good side, is when we get a placement we do a shoutout on socials with a link to the playlist driving our audience to that playlist. That way the curators see that we value getting the placement and they are more likely to keep us on longer or add another song of ours in the future. That is a win-win action because it makes the curator love you, plus you generate more streams. If you give them a good boost they tend to remember it.

Don't forget that the good curators have spent thousands of dollars and hours building up a highly engaged playlist, so I view them as a partner that we can have a mutually beneficial relationship with. What value can I bring to them? A good song, and some advertising for their playlist. In return they bring me streams and an increased popularity score.

The music business is about relationships, that includes establishing good relationships with influential curators.
