An official website of the United States Government (NON-Prod - Development Environment)
– used copy region to “Add Media” then “Create Audio Playlist” from left. Chose 4 mp3 files, then left it like this.
Because Photography Feature Module was used, the “Photograpy” custom field was required, where I had to select an image using the “Image” button (probably an image field type). Chose the redirect graphic.
