Creating Music For Doom + Gameplay

I have been away for some time now i have made some progress on the music side and have been attempting something a little outside of the norm for music creation lately.

Which is creating my own unique and custom songs and injecting them into the doom game, it's a work in progress it's a total of 9 levels and potentially a menu song to make i have made 4 levels so far.

And I wanted to share what I built for the first 3 levels of the game so far

hope you like it.
