AI music for YouTube videos: tracks you actually own.

A song generated from your own prompt and your own lyrics is yours to use on YouTube under the app terms, including on monetized channels. That covers intros, background beds, outros, Shorts sounds and full music videos. Three things are not covered, and they are the same three things that cause claims:

• Covers of existing songs. A cover keeps the original composition. Even a perfect AI performance of someone else's song is still their song, and Content ID will match the melody or the lyrics. Octa screens cover requests and refunds the credit when it blocks one; do not try to route around that on YouTube.
• Prompts that name real artists. The content filter stops those runs anyway, but the principle matters: "sounds like" a named artist is a rights problem waiting to happen.
• Lyrics you did not write. Pasting a poem, a book passage or a famous chorus into the lyric box makes the song derivative of that text.

Original prompt, original words, your track. Everything else is someone else's.

YouTube's disclosure rule for altered or synthetic content is about realistic depictions of people and events, not about background music. You do not need to label a video because its soundtrack was generated, though there is no harm in a line in the description.

Background music has one job: support the picture without stealing attention. That changes the prompt. You want fewer hooks, steadier dynamics and, for most uses, no vocals. Octa's instrumental mode is the switch to flip; the prompt does the rest.

• calm lo-fi instrumental for a study vlog, soft piano and vinyl crackle, slow, no vocals, steady from start to end
• bright indie-pop instrumental for a travel vlog, acoustic guitar and claps, upbeat, no vocals
• minimal electronic instrumental for a software tutorial, soft pads and light percussion, 90 bpm, no vocals, no drops
• cinematic instrumental for a documentary intro, strings and low brass, slow build, no vocals
• energetic phonk instrumental for a car edit, distorted 808s and cowbell, 140 bpm, no vocals

Two words do most of the work: instrumental and steady. A track that builds to a chorus fights your voice-over; a track that holds one level sits under it. For Shorts, flip that: you want a hook in the first three seconds, so ask for "starts on the chorus" and keep the vocal.

Octa generates a complete song, typically two to three minutes. For a ten-second intro that is too much music, and cutting it in an editor works but often lands on an awkward bar. Three cleaner options:

1. Ask for a short form in the prompt. "Short 20-second intro sting, ends on a hit" produces a track built to end, not a fade.
2. Use the extension feature backwards. Generate the sting, then extend it if you later need a longer bed. Extending keeps the same key and sound, so the intro and the bed match.
3. Cut on the downbeat. If you do trim in your editor, cut where the kick lands, and add a 300 ms fade. Every Octa track keeps its tempo steady, so the bars are easy to find.

For Shorts and Reels, generate the full song, pick the 15 seconds with the hook, and keep the rest for a second video. A song you own can become five sounds.

The most common mistake is not the music, it is the level. Music that sounds right on its own is too loud under speech. A few rules that hold on every channel:

• Voice around -16 LUFS, music bed 18 to 22 dB lower while someone is talking. Bring it up 6 dB in gaps.
• Cut the music between 2 and 4 kHz by a couple of decibels where speech lives; a shelf, not a notch.
• Ask for tracks without a lead melody in the mid range: "pads and bass, no lead" leaves room for the voice.
• Use the stems if you have them (Standard and Premium plans): drop the melody stem under speech and bring it back for the transitions.

If you use the same track across a series, keep it at the same level in every episode. Viewers notice inconsistency long before they notice a track repeating.

Content ID matches audio against reference files that rights holders upload. A song you generated from an original prompt has no reference file anywhere, so there is nothing to match. Claims on original AI music come from two sources: a cover you should not have made, or another creator who uploaded your song as their own reference. The second is rare but real, which is why proof matters.

Keep three things for every track you publish: the prompt, the generation date, and the original file from your Octa library. All three are stored with the song in the app; the library entry itself is a timestamped record. If a claim ever appears, you dispute it with those, and disputes over original music with documentation are routinely released.

Channels that use AI music well treat it like a house style, not a stock library. A workflow that takes ten minutes a week:

1. Write one style line for the channel: "warm lo-fi, piano and soft drums, no vocals, steady". Reuse it, changing only the mood word per video.
2. Generate three candidates per video, pick one, keep the other two for future episodes.
3. Store the prompt and the date in your editor project notes. The library keeps them too, but redundancy is cheap.
4. Add a line to the description: "Music made with Octa from an original prompt." It is not required, but it answers the question before a viewer asks it.

Your first song on Octa is free, without a card, and the free tier covers up to four songs. A channel making four videos a month can run on the Basic plan for a long time; a daily Shorts channel wants Standard for the stems and the volume. Both use the same engine, so the sound does not change when you upgrade.
