We will always be adding more content to NLP Eternal as we have access to a vast back catalog.  Before it gets added to our programming, it gets a run through re-mastering and clean-up.  So your favorite may just be in the queue waiting for its turn!  That all being said, keep in mind we do not have the rights to everything, so it's also possible that what you're looking for is not available to us.  Feel free to send us a ticket through the support link and let us know what you're looking for so we can see if it's on the list or if we can send you in the proper direction.
