DistroKid is capable of sending an extreme amount of detailed metadata to streaming services. Which is awesome!
More info here.
Some services can handle it all. Others only have the capability to accept a small portion for now—but likely more in the future.
We'll monitor each service partner, and continuously update them with the maximum amount of metadata they can handle at any time. Most are starting with songwriters and producers.
Please note that credits may take 1-2 weeks to appear in any services that accept them.
