Yes, you can distribute public domain content through Unchained Music, but with some conditions. Here's how it works:

• Part of a Larger Work: Public domain content can be included as part of a larger work, such as a remix or adaptation. However, you generally cannot distribute it as a standalone work.
• Proof of Public Domain: We may request proof that the content you're using is indeed in the public domain. This helps ensure that copyright is respected.

So, while public domain content can be used creatively, it's essential to incorporate it into your larger artistic expression rather than simply distributing it on its own.
