For all it's faults, the music from earlier versions of Factorio was actually quite good. ruhroh took it upon himself to recreate that music at a much higher level of quality; this mod adds it back to the rotation.
You can update this yourself. Open the info.json file in a text editor from file explorer, change the version from 0.14 to the latest version, save the change and reload the game. It works on my end.
