How trending sounds work, and how to post with one

What is a trending sound on TikTok?

It’s a sound a lot of people are suddenly posting with. That can be a hit song, a track from 2006 or ten seconds somebody filmed on their phone. TikTok, Instagram and YouTube Shorts each give a sound a page that gathers the videos made with it: tap the sound on any one of them and you see the rest. What makes one trending is speed: how fast new videos land on that page, more than how many it holds in total. That’s what finding trends early is about.

A sound also travels further than the clip it came from. @novoreel posted the AI white cat singing the opening of Akon’s “I Wanna Love You” on 1 Oct 2026. By 15 Oct that post’s sound and two later ones from the same account sat under about 6,500 videos between them, and most of those weren’t pets at all: they were people lip-syncing to the cat.

What does “original sound” mean on TikTok?

It means the audio arrived with the video, rather than being picked from TikTok’s music library. TikTok names it after the account that posted it, as in “original sound – novoreel”, and from then on anyone can use it in their own video. So the label tells you who uploaded the audio, not who wrote or sang it.

That’s why a famous song can hide inside an original sound. The Smalltown Boy cats dance to Bronski Beat’s 1984 song, yet on TikTok the clip’s sound is “original sound – Bellvtrix”, created on 2 Oct 2026, the day the AI artist posted it. If what you want is the song’s name, the sound page often won’t say; our list of AI trend songs will.

Instagram handles it differently. Its help center says that when it detects licensed music in audio you recorded or uploaded, it switches the credit from Original Audio to the artist and song, and adds the Reel to that song’s audio page. We looked at the Instagram source posts behind three of our trends on 16 Oct 2026: two show a song’s name, one says Original audio.

How the sound is credited on five viral clips

Each row is the clip the remakes copy. Instagram credits as shown on each Reel, logged out, on 16 Oct 2026; TikTok credits and counts from our trend pages, read 14–16 Oct 2026.

Instagram can change a credit after a Reel goes up (its help center says it may relabel licensed audio uploaded as original), so these may move.

Why your AI video keeps the clip’s own sound

A face swap changes the faces and leaves the rest of the clip as it was, and the audio is part of the rest. So your video comes back with the clip’s sound already lined up with the moves, the mouths and the cuts.

On 7 of the 8 trends live on 16 Oct 2026 that audio is the trend sound: the beat and freestyle on Bulin 47, the songs under Hotel Lobby, Raindance, Alors on Danse, Burning Bridges and Smalltown Boy Cats, and the singing cat on I Wanna Love You. Post those as they are. Adding the same song again from the app’s library would play it twice, a fraction out of step, unless you turn the file’s own sound right down and line the new copy up by ear.

We don’t add a TikTok sound to your file. Sounds live inside each app, and picking one there is what credits it and puts your video on that sound’s page; Instagram’s help center says a Reel with another creator’s audio or a library track is attributed to them and shows on that track’s audio page.

How to use a sound from another TikTok video

For a finished video like yours: save the sound first, then add it while you edit the upload. Button names move between app versions; these are the ones in the guides we read on 16 Oct 2026.

1. Open the remake you’re copying

   Pick the version you want yours to sit beside, or check two or three of them. The sound’s name runs along the bottom, and the round icon in the bottom-right corner opens its page. If several remakes show the same sound, use that one.

2. Save it to Favorites

   On the sound’s page, tap Add to Favorites. Use this sound opens the camera to film something new, which you don’t need when the video is already made.

3. Upload your video

   Tap + and upload the video you saved from us from your camera roll. Its own sound starts playing straight away.

4. Add the sound

   Tap Add sound at the top of the editor, open Favorites and pick the one you saved. Drag along the waveform to choose which part plays, so the beat lands where the moves do.

5. Balance the two

   Tap Volume. Original sound is your file’s audio and Added sound is the one you picked, each with its own slider. On Rumpelstiltskin, take Original sound to zero so only Riff Raff plays.

6. Paste the caption and post

   Copy caption on your result gives you a ready line with hashtags, #aitrend and #fyp among them. Paste it in and post.

How to use trending sounds on Instagram Reels

Instagram says audio, not sound. Its help center lists three kinds you can put on a Reel: your own original audio, another Reels creator’s original audio, or a track from its music library.

1. Save the audio from the Reel you’re copying

   Tap the audio name at the bottom of that Reel. Its audio page lists other Reels using it: tap the save icon in the top right, or Use audio to start a Reel with it now. Saved audio waits in your profile’s menu under Saved, then Audio.

2. Start a Reel with your video

   Make a new Reel from the video you saved from us, then tap Next.

3. Add the music

   Tap Audio at the bottom, then Music, and choose the track. Use the slider to pick which part plays, then tap Done.

4. Set camera audio against the music

   The sound already in your file shows as Camera Audio on the left; the track you added sits on the right. Drag the bar under each to set its volume: keep Camera Audio up to keep the clip’s sound, or pull it down to replace it.

5. Share it

   Tap Done, then Next, and share. If Instagram spots a licensed song in your clip’s own audio, it may credit the artist and add your Reel to that song’s audio page by itself.

How to use trending sounds on YouTube Shorts

YouTube’s help center gives two ways in, plus one for a video you upload.

1. From a Short with the sound

   In the YouTube app, open the Short and tap Sound in the lower-right corner to see other Shorts with the same audio. Then tap Use this sound to create a Short.

2. From a long video

   Under the video, tap Share, then Remix, then Use this sound. YouTube says you can sample up to 90 seconds of a music video, though some are limited to 30. Raindance and Hotel Lobby both started as YouTube videos.

3. On a video you upload

   In the Shorts editor, tap Sound and pick a track, then tap Volume to balance the music against your video’s original audio.

4. Mind Content ID

   YouTube warns that copyrighted music in a Short made outside its own tools may get a Content ID claim or be removed. Your file carries the clip’s song on most trends, so on Shorts you can turn its own audio all the way down and add the song with Sound instead, if YouTube’s library has it.

Why can’t I use trending sounds on TikTok?

Usually it’s the account type. Hootsuite’s 2026 guide sets it out: personal accounts get TikTok’s whole music and sound catalog, while business accounts are restricted to the Commercial Sounds library, tracks cleared for commercial use. TikTok calls it the Commercial Music Library and counts over a million tracks in it, Soundstripe reports, but it doesn’t hold every trending clip. So a business account can tap a remake’s sound and still not be able to use it.

To switch back, Hootsuite gives the path as Profile, the menu, Settings and privacy, Account, then Switch to Personal Account. It also warns that your analytics history may be affected, and says TikTok recommends picking one type and sticking with it.

Instagram draws the same line. Its help center says the licensed music library is meant for personal, non-commercial use, so certain business accounts and certain kinds of post don’t get it, and some music isn’t offered in every country. Those accounts can use Meta’s Sound Collection: over 14,000 royalty-free songs and sounds. YouTube says its Shorts audio library is free to use, but only for personal, non-commercial use.

If you post for a brand, remember the song in a remake still belongs to the people who made it. Our terms let you use what you make for yourself and post it on social media, and say the music stays its owners’; posting it is your call, under each platform’s rules. This is how the apps describe it, not legal advice.

Four trends and what to do with the sound

Stages and plays as read on 16 Oct 2026. Add a selfie (or a pet photo), see a free preview in under a minute, and decide on the sound when you post.

1. Rumpelstiltskin Dance↗ Rising ≈57M views · 1–2 people · 9s The one where you add a sound. Your file has the film’s music; the TikTok wave runs on Riff Raff’s track, and the earliest edit we found on it had 5.8M plays on 16 Oct. Save that sound, add it, slide the original down. Still rising. See yourself in it
2. Bulin 47↗ Rising ≈380M views · 1 person · 15s The sound is the street itself: a dembow beat off a portable speaker and an improvised freestyle, kept exactly as it was filmed. Instagram credits it to “Dame Hombro”. Just you under the red lights, still rising on day 15. See yourself in it
3. I Wanna Love You↗ Rising ≈55M views · 1 pet · 10s Your pet takes the white cat’s place and sings to the clip’s own sound, the cat’s song everyone borrowed. Post it as it is. Still rising, with new pet versions every day. See yourself in it
4. Raindance ≈200M views · 2 people · 28s The song is the music video’s own audio, so the pier, the look back and Dave and Tems all come in one 28-second file. Two photos, one for each of you, and nothing to add. Rising. See yourself in it
