I first intended this concept by Helena https://aminoapps.com/c/songwriter/page/blog/acidic-thoughts/aPa5_M4i0uo88jbmdLxMzxYEBrKjb7znxiE - to be a slow rock song in the style of Black Hole Sun by Soundgarden. In the end it became a experimental electronic track in an upbeat tempo.

Music has no boundaries, neither do our favorite pink pony. But one part of her she wished had been out of bounds, even for her.

Lyrics:

Thinking terrible things
Thought eating away at me
Thinking dangerous things
Thought that petrify me

Stop looking at me
I don't wanna see
The pony I long to be
Acidic thought
Though it doesn't look that way
Acidic thought is here to stay

Swirling in my brain
Dangerous thoughts
Feeling the pain so long
Felt it so long
I'm going insane
Closing the door on society

That mirror is me
Wish it wasn't you
I love you with all my heart
Acidic thought
We made ourselves a work of art
Acidic thought tears me apart

Though we're the same
I will never be
The pony that you became
Acidic thought
Though it doesn't look that way
Acidic thought is not my name

That mirror is me
But you are not me
Acidic thought

We'll never be friends
Pinkamena Pie
Acidic thought
Acidic thought

We'll never be friends
Pinkamena Pie
Acidic thought
