A recording, for the purposes of licensing, includes any fixed media object, from physical manifestations (CDs, DVDs, LPs, etc.) to digital fixity (mp3, wav, mp4, mov, etc.). Any saved audio or video live stream is a recording.
Recordings of copyrighted works must be licensed for distribution, both in a physical format or through an online platform.
To date, there is no blanket mechanical licensing available, but in the next two years that should change. The Music Modernization Act (2018) established the Mechanical Licensing Collective, which is set to begin issuing blanket licenses for mechanicals starting in 2021.
Until such a license is available and the University of Iowa commits to obtaining it, works must be licensed individually through either the Harry Fox Agency, the Mechanical Licensing Collective, or other rights holders.
The Harry Fox Agency administers mechanical licensing for the over 21 million works in its catalog. Their platform Songfile is used to administer licensing of recordings. To search the HFA catalog available in Songfile, you must register for an account.
The Mechanical Licensing Collective is a non-profit organization that administers blanket mechanical licensing for digital service providers (e.g., Spotify, Apple Music, Google Play) and distributes royalties to rights holders. The MCL has a publicly searchable database of musical works.
