I can read Japanese, as well as about 7-8 other languages, if you are interested. But no, I did not "post" that reference, and please don't write in a language I assume you cannot write in. In fact, please don't live in a world I assume you should not live in.

No article is prohibited as a use for reference. Use of reference has nothing to do with copyrights. Study your books.

If sales information are unencyclopedic, I guess we should delete the List of best-selling music artists instead of discussing about it, right? We won't see them on the Japanese Wikipedia because the Japanese Wikipedia, frankly, sucks.

Take care. |heru|nar
