Short with one licensed track: half the revenue covers the music

On a monetizing Short with one music track, half of the revenue tied to its engaged views goes to the Creator Pool and the other half covers music licensing. That is the example YouTube's Shorts monetization page gives, and the same page says accepted monetizing partners keep 45 percent of the allocated revenue regardless of music use (read 2026-10-03).

The page also says that for this calculation only music from YouTube's music partners counts as a third-party contribution; other third-party content categories do not currently change the pool allocation. So a Short with a licensed track and a Short with only your own voice and footage are treated differently on the revenue side, even before anyone asks whether either is original.

What the page says, and what it does not

Read the page as an accounting rule, not as a recommendation signal. The October 2026 update to Shorts recommendations is about original versus re-uploaded clips, and it is reported to leave monetization under the existing reused-content policy. Music licensing is a third thing again.

The page does not address AI-generated music, and I found no sentence that says a generated track is outside the licensing share. Do not assume it is. If the revenue split matters to you, test one Short each way and read what Studio reports.

Two ways to give a Short a soundtrack from Sume

If you want music that is not a library track, Music 1.0 generates music from a text prompt on Google Lyria 3.5. The docs describe full-length structured songs up to a few minutes, steered by the prompt, and note there is no duration parameter, so you ask for length in words. The prompt is a creative direction, not a guaranteed setting: verify the audio. New integrations are pointed at the Music Router.

Then lay it under the picture with Timeline 1.0. The soundtrack field takes a bed with gain_db, loop, fade_out_seconds up to 10 and duck_db of 0 to 20, but ducking needs a real audio spine, not silence. A spoken Short can therefore carry a quiet generated bed that drops under your voice.

A small decision rule

Sume does not guarantee reach or earnings, and a generated soundtrack does not make a reused video original. Originality still comes from your footage, your script and your edit.

• Voice-led Short that needs no music: skip the track; there is nothing to split.
• Short where a licensed library track is the point: expect the half-and-half split on its revenue.
• Short with a generated bed: treat the revenue treatment as unknown until you have seen your own numbers.
• Any Short built on someone else's audio as the whole point: that is an originality problem before it is a revenue one.

How to test it on your own channel

Because the page is silent on several cases, the only reliable answer is your own data. Pick two Shorts of similar length and topic that you made yourself. Publish one with a licensed library track and one with only your voice or a generated bed. Then compare what Studio reports for each after the same number of days. Two Shorts are an anecdote, not a study, and engaged views vary a great deal by topic and timing, so repeat it a few times before you change how you work.

Keep a note of the audio source for every Short you publish. If YouTube later clarifies how generated audio is treated, that note tells you which of your videos were affected. A one-line spreadsheet column is enough: Short title, audio source, whether a library track was used.

Where this connects to the originality update

The October 1 change is about recommendations: YouTube says it is prioritizing original Shorts and reducing reach for channels that mainly re-upload other creators' clips (Search Engine Journal, read 2026-10-03). A music choice does not turn a reused clip into an original one, and the monetization page lists songs that are only pitch- or speed-modified copies as not allowed. Music is a revenue-accounting detail on a Short that is already yours.

If you are deciding where to spend effort this week, spend it on the footage and the script. Choose the track last.
