Help with a japanese license for music in a videogame

["Miriam Ruiz" <little.miry@gmail.com>]

Hi! :)

HIZ's game Tatan [1] includes music licensed under this license [2]:

http://www.geocities.jp/cyber_rainforce/siyoukiyaku.html

Google translation says:

http://64.233.179.104/translate_c?hl=es&langpair=ja%7Cen&u=http://www.geocities.jp/cyber_rainforce/siyoukiyaku.html

And it seems to be DFSG-free, so I don't have to remove it. Can anyone
confirm it?

If it is DFSG-free... will anyone be able to make a translation of it,
even if it's brief, to put in the debian/copyright file?

Thanks!! :)

Greetings,
Miry
