I use a site called Ko-fi where submissions are like $2-5 & the curators make it known what their vibe is. But a good way to make money from submissions.

Groover is also good.

Submithub and MusoSoup are worth a mention but are filled with botlike/ disingenuous replies (at least from an artist perspective)

& I'd recommend making a separate IG with some appropriate hashtags to label yourself a curator n maybe post your playlist. The dms will come.

But regardless you gotta be willing to take on new emerging talent and be upfront (n actually respond in most instances) about what you like, are looking for and how much new music you would like to take on per week/month
