http://www.playstation.jp/scej/title/wa4/

the above link is the official website of the PS2 game Wild Arms 4
when you get into the website, it will automatically play a theme song of the game.

Can someone tell me the name of the song and the name of the artist?
You can either tell me in Japanese or English

But please post those names as a message, so I can copy and paste the name.

Thank you to the person who can answer my question.
