"Push (Feelin' Good on a Wednesday)" (aka "Ya ya ya, I am Lorde"). Has a catchy beat, sounds like an authentic Lorde song, and the song actually sounds like a call for acceptance of who one is and a defiance of others' disapproval.
The Circle of Poo. It sounds like some joke parody of "Circle of Life", but it sounds so fucking glorious. Especially Cornwallis' singing voice near the end.
