This WeakAura will play the Attack on Titan Season 1 Opening theme when Rain from Above is used. (NOTE: Requires sound file to work!)
Sound file must be placed in the "World of Warcraft\_retail_\Interface\AddOns\SharedMedia_MyMedia" folder to work. (Either create the folder in your AddOns folder, or you'll have to edit the WeakAura's Actions > Sound File Path.)
