The claim and the verdict
The claim: If an old song is in the public domain, any recording of it can be placed in a podcast or video without permission. The verdict is false. This is a creator’s rule check, not a finding against a named performer or publisher. The date of a composition alone cannot establish the rights in an audio file.
The U.S. Copyright Office separates a musical composition—the music and accompanying words—from a sound recording, the fixed performance. The composer and lyricist can be different rights holders from the performers or producer responsible for the recording. Copyright in one work does not substitute for copyright in the other.
An archive is a useful test case
The Library of Congress’s National Jukebox rights statement explains why recording dates matter. It identifies separate protection periods for historical recordings, including a 100-year term for recordings published from 1923 through 1946 and a 110-year term for those published from 1947 through 1956. Those are recording rules, not a universal expiration date for the underlying songs.
The practical comparison is a new performance of an old composition. Even if the underlying music is confirmed to be public domain, a recently recorded performance is a different work. Conversely, a historical recording’s availability in an online collection should not be treated as a blanket reuse license for every item in that collection.
What a usable clearance record should identify
For a proposed podcast opening or video soundtrack, record the composition’s title and version, the performer, the particular recording, its publication information, and the permission or public-domain basis for each relevant layer. A download button or attribution line does not answer those questions.
The Copyright Office also recognizes that original arrangements and other derivative versions can contain new copyrightable authorship. Making your own recording therefore removes reliance on someone else’s master recording, but it does not automatically clear a protected arrangement. This verdict addresses the blanket claim; it does not determine the status of an unnamed track, a particular license or a specific fair-use argument.
