Music Licensing and Stems: What Producers Need to Know

The legal landscape around AI-extracted stems is still evolving, but the fundamentals of copyright law are clear. Understanding them protects you as a creator and keeps your work commercially viable.

Two Layers of Copyright

Every commercial recording has at least two separate copyrights:

1. The composition — the melody and lyrics, owned by the songwriter(s) or their publisher
2. The sound recording — the specific recorded performance, owned by the record label or artist

When you extract a stem from a released track, you're working with the sound recording — the second layer. Both copyrights must be licensed separately for commercial use.

What AI Extraction Doesn't Do

AI separation is a technical process that transforms how the audio is organized. It doesn't create a new copyright, and it doesn't affect the original copyright. An extracted vocal stem is as protected as the original track — it's still the same sound recording, just isolated.

Fair Use and Equivalent Doctrines

In the United States, fair use may apply if your use of extracted stems is:

• Transformative — you created something new and distinct
• Non-commercial — for personal or educational use
• Not affecting the market for the original

Fair use is a defense, not a right — it's evaluated case by case. Switzerland (where Stemify operates) has equivalent concepts in the Swiss Copyright Act (URG), particularly for private use (Art. 19) and quotation rights.

Remix Licenses

If you want to officially release a remix based on extracted stems:

• Contact the publisher for a synchronization or derivative works license (for the composition)
• Contact the record label for a master license (for the sound recording)
• Many artists now offer remix competitions through distrokid, Splice, or their own sites — these come with pre-cleared licenses

Sample Clearance

If you're using extracted stems as samples in a commercial release, sample clearance is mandatory. Uncleared samples — even heavily processed ones — have led to successful copyright lawsuits. The test is whether an average listener could recognize the original source material, not whether you technically altered it.

The Safe Path

For commercial production: extract, study, and draw inspiration from stems — then recreate the elements you want using your own instruments and performances. This is how professional producers work around copyright while still being influenced by existing music.
