The song was used without permission of the artist. This is why it's not credited. According to him, he was approached by a media group who commissioned him to write a song, which he did. The media group later sold the rights to the song (which they had bought from the artist) to this show. The artist's name is Assasi and unfortunately, that will not help you find the song because he doesn't own it. I'll save you some time: none of his songs on any streaming platform is the one you want, although you should check those songs out because they're cool.
It's really shady that the show used his song but won't even credit him. Or tell us where to find it...
