Where's the Buildism theme song?

[Rizou]

Here's the MP3 format ready-to-use:

I have it posted somewhere on Buildism as a re-extensioned .bsmodel, but you have to re-extension it as an mp3 and this is quicker and I don't have to search it up.

I swear I heard those types of sounds somewhere.

P.S. It does sound horror-like.
