Can an App's TikTok Use Trending Sounds? Music Rules
Short answer: no, at least not the trending sounds you're thinking of. If your TikTok account exists to promote your app, the viral songs and chart hits in the general Sounds library aren't licensed for that. Switching to a personal account doesn't change it either. Below is why, the three options you do have, and how to build a post that works without a trend carrying it.
Why the sound you wanted says "unavailable"
TikTok runs two music catalogs:
- General Sounds. This is the big library with trending songs and viral creator audio. TikTok's Music Terms say you shouldn't use a recording from Sounds for any commercial purpose. They describe Sounds as being for personal use.
- Commercial Music Library (CML), which TikTok calls Commercial Sounds. These tracks are cleared for brands. TikTok's ads help center describes it as a global library of about 1 million songs that are free for businesses to use in organic or paid content.
When you tap Add sound on a Business Account, TikTok's help page says you will only see sounds from the Commercial Music Library. So the trending song you saved on your personal phone shows up as unavailable on the app account.
If you post anyway, by uploading a video that already has an unlicensed track baked in, TikTok's content matching can flag it after it goes live. The usual result is a muted video. Repeat it and you risk copyright strikes on the account you're trying to grow.
"I'll just switch to a personal account"
That's the tempting fix, and it doesn't work. Two reasons:
- The rule follows the content. The commercial restriction is about what the video does, not what kind of account posts it. GEMA, the German music rights society, sums up TikTok's Music Terms this way: what matters is whether the video serves a commercial purpose, not whether it's on a commercial account. A video showing off your app's features is marketing.
- TikTok's terms cover it. The US Terms of Service bar using TikTok Content for commercial purposes unless that use is permitted, and the music in the Sounds library counts as TikTok Content. A personal account that's really a brand account still has to follow that rule.
You'd also lose the Business Account tools you'll want later, like analytics and the Creative Center. And if a label later claims the audio, the strike lands on your app's account.
The three legal options, and what each costs you
1. The Commercial Music Library
Effort: low. Reach cost: you can't ride a viral song's momentum, because most chart hits aren't in the library.
This is the default choice. Two ways to find something that isn't dull:
- In the app, tap Add sound. On a Business Account, the search only returns CML tracks.
- On desktop, open TikTok's Creative Center, go to Trends > Songs, and turn on the Approved for business use filter. TikTok's help article says songs with that label are royalty free, and you can still sort by Popular and Breakout. That gives you the CML songs that are trending right now, which is the closest legal version of trend riding.
TikTok's help page also says the CML shows up to 10,000 sounds at a time, so search and filter by mood, genre and length. Scrolling the default list won't get you far.
2. A track you license yourself
Effort: medium. Reach cost: about the same as the CML, and you pay for the license.
You can buy a license from a stock music service and upload a video with that track already mixed in. Two things to check first:
- The license has to cover commercial use on social platforms, TikTok included. A YouTube-only or personal-use license isn't enough.
- At upload, TikTok may ask you to confirm you hold the rights (the Music Usage Confirmation). That's your own statement, not a clearance. If the track's publisher uses content ID, keep your license receipt so you can dispute a false claim.
This is worth doing when you need a specific sound for brand consistency, for example the same sting at the end of every post.
3. An original sound made for the post
Effort: medium to high if you produce it yourself. Reach cost: none from licensing, because you own it.
When you post audio you made yourself (a voiceover, a beat, a short jingle), TikTok saves it as an original sound under your account. Other people can reuse it, and that's the only way a brand account gets its own trend started. Don't plan around that happening. Plan around the sound fitting the video.
An original sound also can't be muted for copyright later, which matters if your best post is going to keep pulling installs for months.
Make the post work without a trend
A trending sound mostly gives you borrowed attention for the first second or two. Without it, the video itself has to earn that attention. Three things do most of the work.
A hook that shows the result in the first second
Don't open on your logo, a splash screen or "Hey guys." Open on the payoff: the finished try-on, the plan the app generated, the before and after. The viewer should see what your app does before they decide whether to scroll.
On-screen text that works with the sound off
Plenty of people scroll muted. Put the promise on screen in plain words, large enough to read on a phone, and keep it clear of the caption and the right-side buttons. One line per scene.
A voiceover that carries the story
Once the music isn't the main event, a voiceover does what the trend would have done: it sets the pace and tells the viewer why to keep watching. Keep the music under it at low volume.
Here's a brief you can reuse for a 15 to 20 second app post. Fill in the brackets and shoot or build it scene by scene:
POST BRIEF: no-trend app video (15-20s)
0.0-1.0s HOOK Show the result on screen: [finished output of the app]
Text: "[result] in [time] with one photo"
1.0-4.0s PROBLEM Text: "I used to [painful old way]"
VO: same line, spoken
4.0-12.0s HOW 2-3 scenes of the real app: [input] -> [tap] -> [output]
One text line per scene, max 6 words
12.0-16s PROOF The result again, closer or side by side
16-20s CLOSE Text: "[app name] on the App Store"
AUDIO Commercial Music Library track OR licensed track OR original
Music at low volume under the voiceover
CHECK Readable with sound off? Result visible in frame 1?
Judge this format over a week of posts, not one. A new account's first videos often sit near zero no matter how good the hook is. That's about the account, not the post, and our guide to 0 views on a new TikTok account explains what to do during that first week. How often you post matters as much as any single hook: a steady schedule of decent hooks beats one perfect video followed by a two-week gap.
Also keep most of your mix as videos. Carousels get far less reach than videos for most accounts because they carry no watch time, so a carousel with a CML track won't make up for missing video posts.
Where Social Studio fits
Social Studio makes TikTok posts for app makers and gets around the licensing problem by not using borrowed audio at all. Every post gets an original music track made for it, a voiceover from a catalog of 200+ voices, and on-screen text, and it's built from your real product photos. Nothing goes out until you review it and press Post. You can see real examples on the samples page, and TikTok marketing for apps explains how the whole thing works.
The rule of thumb
If the video sells your app, use a CML track, a track you licensed for commercial social use, or audio you made yourself. Then put your effort into the first second, not into chasing the sound of the week.
