The audio playlist is a native WordPress feature and can be used in the classic editor, or block editor using the classic block. It uses mp3 files uploaded to the media library and very similar to creating an image gallery. In order to create an audio playlist in Elementor, you will need to use the Text Editor Widget.

Tip: Video Playlists may be created using the same steps above.
Note: Since this uses the media library and is stored in the uploads folder, the files can be downloaded by users using the developer tools or inspecting the code. It is recommended to upload clips or lower quality files if important to protect this from occurring.
