How to Add Music to a Video for Instagram

The fastest way to add music to a video for Instagram is to use the Music tool in the reel creation menu and pick from Instagram's audio library, which keeps the track licensed and credited. Here's how that works, and what happens when a track stops working.

Add music to a video for Instagram from the in-app library

Instagram documents a Music tool in the reel creation menu for searching its audio library. Tracks used this way are copyright-protected content that Instagram licenses, and its Help Center is clear that such content must be credited to the artist with the track name included, which the platform handles by attaching it to the post.

That attribution is the point of using the library rather than importing a track yourself. It's the difference between a track Instagram knows about and a track it has to identify.

What happens when a licensed track gets muted

This is the part worth knowing before it happens to you. Instagram's Help Center explains that it has agreements with music rights holders to protect artists, and that changes to those agreements can result in audio being muted. The reel doesn't come down, it stays visible, silently.

There's a recovery path, and it's narrow. You tap Audio unavailable, then Replace audio, choose a new track, and tap Done. Instagram notes that a muted track can only be replaced once.

One replacement. That's worth treating as a real constraint: if a track on an old, well-performing reel goes silent, the substitute you pick is permanent. Not a decision to make in thirty seconds on a phone.

Montaj doesn't add music. It makes the voice worth mixing

Straight answer: Montaj has no music feature. There's no audio library and no track import, and adding music happens in Instagram or wherever else you're pulling audio from.

What it does is everything that should happen to the voice before music arrives, and that work is worth doing first, because a track laid over a noisy, silence-padded recording can't be mixed into something good afterwards. Montaj transcribes the audio, removes the dead air in one tap, and runs an on-device denoiser over the voice. All of it happens locally: the audio never leaves your device, which matters more than usual on a page about music, because the audio track is precisely the thing that gets scanned, matched and flagged once it's uploaded anywhere. Get the voice right on your own hardware, then add music to a video for Instagram in the app that licenses it.
