Baten Kaitos/Headscratchers

I could swear I've heard the music "Deterioration" (the theme that plays in the Ancient Library of Magic) in other places. For example, the Hi Hi Puffy Ami Yumi Show and some TV commercial. Can anyone help me with this? Larikush speaks of blue blood as hypothetical... while Kalas is carrying around half a dozen lobsters...
 * Likely pure coincidence. Many songs sound alike and have similar sounding melodies.
