Lyrics:

Eridan is not that great you need to shut up now
Even though you think he's great, he is really not
You all think he's really great, even though he's not
You think he should have his song, here it is right now
Eridan is not that great and he does not deserve a theme

Oh, Nick Smalley guitar solo
