I appreciate the feedback. Getting the music to loop was a struggle. I tried a few things and none of them stuck. Do you know how to get audio streams to consistently loop?

The loop setting is not on the audio stream itself, I also struggled a little with it, you actually need to double click the audio file inside the editor file system, it will open the import window, there will be a check box for looping, check enabled and click reimport. Then when the music finished Godot will automatically play it again.
