RoastedNareth (And Nareth's sister) were correct!  It was "Revolting Children" from Matilda! 

My sister was Matilda, meanwhile I'm struggling to understand why my own director lacks so much faith in me after how much effort I put into yesterday's audition only to get absolutely thrown to the side.  Heh.  Don't worry this is the second time in three or four months, plus show choir around nine months ago. Man, no wonder so much of my self-confidence comes from things that AREN'T performing arts despite me wanting to be in it so badly.

Ok enough about that, onto the next song!

Difficulty: Easy

Trapped within these walls

You left our souls to drip away

The ink decays, the walls at bay

But the reckoning has come today

You say

Boris has no guts 'cause you replaced it with mechanical strain

We've been tortured but we move forward

This disorder kills your day!

I cannot express how much I listened to this song last summer-
