How to get the iPhone X’s exclusive new ringtone on your older iPhone

Lifehacker:

One of the many ways Apple sets its smartphones apart from the herd is with special ringtones, dating back to the original iPhone and its iconic Marimba melody. The iPhone X is no different. It features an exclusive default ringtone called “Reflection.”

The first thing you’ll need to do is download the Reflection audio file onto a Mac or PC.

Sounds like a great idea but is their methodology not working for anyone else? Trying to drag the new ringtone into iTunes for me doesn’t get me anywhere.
