Technically, Bleach is a manga (Japanese comic), created by the Japanese manga author Tite Kubo. His real name is Noriyaki, I believe. I'm sorry if there's a random book called Bleach and I am mistaken.
Bleach is Japanese anime, so they speak Japanese. There are some Spanish words thrown in there, and few English.
There is no secret track on the Bleach album. However, the album was re-mastered in 1992, and 2 additional tracks were added at that time.
"Bleach" is originally a Japanese manga and anime series, so it is spoken in Japanese. It has also been dubbed into various languages, including Mandarin Chinese, but the original language is Japanese.
I do not know when it was created, but I can tell you when it was aired. The first episode aired October 5, 2004 in Tokyo, Japan, then Viz media obtained privledges to air bleach episodes outside Japan March 15, 2006.
Bleach is in Japanese but it has been translated into different languages and has been subtitled.
There are episodes of bleach in English and Japanese
