At least Laputa is released here. I failed to mention that I was looking for this soundtrack, soon released by ULM / Universal. I wanted to know if it was the 1986 or the 1999 version of the score. It's clear after seeing the release official site that this is the 1986's one.

By the way, this site is painful, completely in Flash, slow as Hell, with some silly JavaScript blocked by Mozilla (hopefully, I like pop-up prevention) if you reach the normal welcome page.
