Because I want to build a collection. This is a really good (and long) one. It'll never get old, I like the Japanese version better for some reason. But I still know what it says. 
Edit: The kingdom hearts franchise have two openings, Simple and Clean, which is the first, and Sanctuary (english) of the japanese sanctuary (which is called passion)
Hot-linked English opening videos here.
Kingdom Hearts, Simple and Clean; English (PS2)
(Kingdom Hearts 2, PS2)Sanctuary, English
The ones used on the DS versions are the same, but I would check it out (358/2 days for DS, and Birth By Sleep which will be released in NA in September.)
You can always find the Japanese (and the japanese sanctuary, aka. passion I find better in my opinion.)
