Having just watched a Naruto/"Born to Hand Jive" video on YouTube I have to wonder if Doug would be able to use the song to manipulate chakra using the Naruto-verse system (Although he'd probably have to visit the world first and may have to force the lyrics the first time).
Of course, sense he hasn't actually studied Naruto-verse jutsu the easiest thing would be if the power gave him the Sharingan eye for the duration of the song. That way the song would still have a fair amount of potential use even when he leaves the world and can no longer learn new jutsu.
