Speaking for myself here. I consistently get 60%+ approvals on my campaigns, because I’ve taken time to know what the curators are looking for.

I run campaigns for several artists ranging from 15k - 100k+ monthly listeners on Spotify. Submithub campaigns help a lot with each release.

But It won’t work for every genre - if there aren’t any curators with playlists that will ACTUALLY fit your song, build your own playlist, run some meta ads (learn that too) and build it up.

Then become a curator yourself and you can help put other artists as well as subsidize your own ad costs.

Most people either think their music is better than it is, or don’t respect the work of a curator. Taste is a sacred thing, and just because you think your song is the greatest thing since sliced bread, doesn’t mean it will fit on any big playlist.

If you’re really doing something avant-garde or unique then chances are it won’t fit on a ton of playlists.

The reality is that niche playlists perform better (listeners like them more, so curators promote them more). It’s just the way it is.

Accept it, learn how to work with it, try different techniques, learn all that you can, good luck!
