Two things: your song and some credits. Everything else (targeting, ad copy, curator selection, creative generation) we handle.
Your song
You can give us either a Spotify link (which auto-fills title, artist, cover art, and genre from Spotify's data) or upload an MP3/WAV directly the way you would for a normal submission. Spotify link is the faster path if you have one; audio upload works fine if you don't.
Credits
Packages are paid for with SubmitHub credits. You pick the package size; we deduct the total upfront.
What if my song isn't on Spotify yet?
You can still launch a package. Curator submissions start straight away, and the Meta ads portion waits until the song is live on Spotify (ads point to your Spotify track, so it has to exist first). See the "Pre-release songs" article for how that works.
What if I'm not putting the song on Spotify at all?
Curator-only packages (like Branding) work fine on audio upload alone. If you pick a package that includes Meta ads and never provide a Spotify link, the Meta portion will auto-refund after a grace period.
Anything else?
That's really it. No page setup, no copy writing, no creative uploads. If you want to go further (connect your own Facebook page, upload custom videos, tweak targeting), you can do that later from the ad that gets created. But you don't have to.
