You can also browse the copyright-free music library using the search bar. Type in a relevant keyword like a specific instrument, mood, or style of music like Latin or Greek.


Step 2. Preview the audio file

To preview an audio track, click on the play button on the audio file. The music will automatically start playing and you can listen to the full song for free before adding it to your video. Stop listening to the soundtrack by clicking on the same button.
