I prefer to think of this as <i>mermaid marketing</i>. It&#x27;s nice to hear them sing, but don&#x27;t fall for it or they will eat you.<p>Watching theses events is like this famous passage of the Odyssey. Once you are tightly attached, and don&#x27;t risk to go overboard (and start buying stuff you don&#x27;t really need), then enjoy the show. I&#x27;ve been told their exciting song is the <i>most detailed</i> and <i>beautiful</i> thing you&#x27;ve ever heard :)
