Ok! I only picked Celest because it fit best in the title. I started with "Lusternian Idiot", but this came out better. Parody of "American Idiot" by Green Day, though sort of also "Canadian Idiot" by Weird Al. 
Don't wanna be a Celestian idiot
Don't want to be some light-praising chowder head
And do I look like a spit-shine plate paladin?
Don't wanna be some soggy-headed Merian.
They live on coral and seaweed,
Always spewing off the same old creed,
Over-zealous choir day and night.
Worshiping a big shiney puddle,
And some half-addled supernals,
Something up there isn't quite right!
Don't wanna be a Celestian idiot
Don't want to run in circles on Nautilus
Can you hear the Cantors' frantic chorus?
They want to convert every single one of us.
They live on coral and seaweed,
Always spewing off the same old creed,
Over-zealous choir day and night.
Worshiping a big shiney puddle,
And some half-addled supernals,
Something up there isn't quite right!
Don't wanna be a Celestian idiot,
Won't kill of all the herbs with my element,
Who'd want to be some water-logged furrikin?
Just those moldy crack pot Celestians!
They live on coral and seaweed,
Always spewing off the same old creed,
Over-zealous choir day and night.

Funny! I'm really loving all the Lusternia themed parodys!
