The filters down the left side of the curator list narrow it to the curators that fit what you're looking for. Change one and the list updates right away. Some only show up when they apply to you, like the favorites and history ones.
Genres
Pick the genres that fit your song. By default you'll see curators who accept at least one of them. Switch "or" to "and" to see only curators who accept all of them.
Additional filters
Submission history
This appears when you've sent the song before. "Hide those I've already sent to" and "Hide already responded" are both on by default, so you don't send to the same curator twice. "Let me resend to outlets" turns both off. History is tracked per upload, so if you've uploaded the same song twice, each copy has its own. See the "How do I avoid submitting to the same curator twice?" article.
How do they share music?
Choose where you want the song to land: music blogs, YouTube channels, radio, playlists on Spotify, YouTube, SoundCloud, Apple or Deezer, SoundCloud uploads and reposts, or social media.
Approval rate
Set a low and a high percentage, then hit Update. Handy for skipping curators who approve almost nothing.
Country
Show curators from particular countries or regions.
Price
With premium credits, filter by how many credits a curator charges per submission.
Genre match, Quality and Engagement
Three sliders from 1 to 10. Drag either end to set a range. Genre match needs at least one genre selected. See the "What is the "Genre Match" score?", "Quality" and "Engagement" articles.
Credits
Shows curators who take premium or standard credits. While you're submitting, this is locked to the credit type you picked on the first step.
Select all
Ticks every curator left in the list. It's for premium submissions and needs at least one genre selected.
A curator is missing?
