Nico Nico Douga theme songs are medleys and as such, are a combination of snippets of songs that exist in reality.
That being such, full versions of each song exists and you just need to look for them.
In fact, you can find a full list of the songs used and where they come from.
That being such, you can easily GOOGLE each song title or, I don't know, YOUTUBE SEARCH for each song that you are looking for and thus find it.
In fact, why didn't you do that before hand?
Oh, and by remixed, do you mean overlapped with the previous/next song? Well, you won't find full versions of that of course.
Oh, and by remixed, do you mean instrumentals? Well, just look for the karaoke version.

But, of course, this post is useless.
That being such, saging.

Sup Norse mythology, just being a more idealistic hero in a pantheon of dicks.
