I have these two releases on DVD and Blu-ray but can't find listings for them. I can only find the live ep and albums for both of them. Can i list them or is there a reason why i cannot find the DVD and Blu-ray listings on here for both of these releases?

Neither of those are part of Metallica's discography. "Metallica: Through the Never" is a movie, which features Metallica and involved Metallica's input, but which is its own independent project. "Metallica: Some Kind of Monster" is a documentary about the band; we don't include documentaries as part of band discographies.
