You can add background music to your publication to play whilst it is being read.
Please note that any music or audio files you wish to add must be hosted online and available through an URL (for example, https://www............mp3). It is not possible to add a link to a media player that plays the music.
To add background music to a publication, go to the Publications page of your account:
Place your cursor over a publication and click on the Pencil icon.
In the window that opens, select the Customization tab.
Click below Background music URL to enter the URL for your audio file.
Finally, click on the green PUBLISH button to save the changes to your publication.
