If you're lucky enough, you'll find your song. The app can try identifying the song like Shazam and SoundHound, or you can even try putting in the lyrics that you heard on TikTok and search. Download Musixmatch - Besides these two apps, you can also try Musixmatch.SoundHound is available for free on the App Store as well as Google Play. However, it's song library is not as good as Shazam in my opinion. Download SoundHound - Similarly, you can also give a shot to SoundHound.Shazam is available for free on the App Store as well as Google Play. If Shazam is able to recognise the song, you'll see it in the results. Now, take a secondary smartphone > download Shazam from either the App Store or Google Play > launch the app and tap the Shazam icon > now start playing the song on your primary phone. To use this app, open TikTok on your primary phone > select the video from which you want to find the song > pause it. Download Shazam - One of the best third-party apps to recognise songs is Shazam.How to Block or Unblock Someone on TikTok.
