I think I ever tell you about soundtracks but it seems like I will make it clearer to you.

First of all is... "Wikia research suggests that these albums are not sold separately, but were bundled as extra content for the Nichijou DVD/Blu-ray. There are thirteen volumes, each consisting of background music presented in roughly the order it appeared in the anime (albeit very roughly)." - List_of_Nichijou_Albums

And that's why I suggest you take a look into www.blu-ray.com/Nichijou/244394/#Releases if you want to get the soundtracks.

I think that's all I can say.
