Persona 5 Royal Theme is a music track that can be played in the game’s Social Links and Party Quests. To get it, you will need to complete the associated tasks. To start, head to the Social Links section of the game’s website and click on the link for Royal Theme. Once you do, you will be taken to a page where you will need to input your PlayStation 4 account name and password. After doing so, you will be able to access your account’s music library and select Royal Theme from there. If you have not already done so, make sure you have installed Sony’s PlayStation Music app on your device. Once it is installed, open it and select Royal Theme from the list of songs that appear onscreen. If everything goes according to plan, once you play Royal Theme in a Social Link or Party Quest, your PlayStation 4 system will automatically update with new content that includes new songs by composer Hideki Kamiya and lyrics by Shoji Kawamori.
