Lonely Roads PS4 Dynamic Theme 

The PS4 store does not display themes in search results so if you are having problems find this product here are some tips.
Europe - Look up the game Puzzle Showdown 4K. You will find the theme under that game's associated products. You do NOT need to purchase the game for the theme to work.
US - Navigate to Add-Ons, then themes. Filter alphabetically or by release date. The release date should be the same as the release of this video.
