I watched some of that video. It was awesome!

I agree that bosses in future Zelda games should be harder. They should also all be legendary creatures that you would want to sing about. Volvagia would fit into this, but Blizzeta wouldn't. Now who's them song had what sounded like singing in it? Blizzeta. That's wrong. Now, even though Blizzeta appeared in a game for a more advanced console in which it would have been easier to do that consider this: Stallord was at best, more legendary than Blizzeta. What does he get? It's a remix of volvagia's song.

Zelda Ganon's Puppet gets what sounds like singing in the theme music, and the same happens again for the Dark Beast Ganon theme, but this doesn't happen in the fight against Dark Lord Ganondorf, the final boss. That's injustice! Even worse, these songs that sound like they have singing in them don't even have words. It's like a choir was told to moan all day but with style. I know that Nintendo doesn't like using voice acting, but what's so wrong about putting actual vocals with words into a boss's music?

They should also do this for appropriate places. They sort of did that in OoT's temple of time, but again, those were not words. Those were a bunch of "e" sounds.
