Help finding songs

[Azmaria]

well, my Kingdom Hearts fanatismus woke up again after I played the Nintendo DS game, so I was browsing some sites and found the covers in spanish of Hikari and Passion, but I am having such a hard time finding them to download and add them in my MP3. I would also be happy if someone just rips them out of the youtube videos, I am to dumb trying that XD

here are the links of videos, I would be so happy if someone could help me pls ^^
