So I looked around youtube, And I found an underrated mod that is REALLY GOOD, And It has some really good soundtrack. I personally like it.
And since its so underrated, No one uploaded a 'OST' Video or Track anywhere, So might as well be the first to do it.
And Now, Credits where its deserved.

They did a good job honestly, I like it! 
So yea, that's about it. 
Oh, and if the creators of the mod or the youtube creator wants this to be taken down? I'll do so, fine by me.
I simply wanna share this underrated mod honestly, and give it a bit more attention.

(Scrapped) Childs Play V2 -FNF- Pibby Apocalypse

The introduction for this piece of instrumental jazz/rock, starts with a repeated riff played on tenor sax. This is then joined by the soprano sax playing a counter melody, which is repeated with the addition of the baritone sax playing another counter melody.
The main tune is played on tenor sax with a rock/boogie backing, followed by an improvised alto sax solo.
Overall a piece of medium paced (140 bpm) instrumental jazz/rock using a combination of acoustic and electronic instruments.
Composed and recorded July 2025.
