Mandalorian chapter 19 Easter egg

So I was watching (and rewatching) the new episode of Mando, and I caught something. 

During the scene were Pershing is walking around with Kane (as seen in the picture)

Now, when they start getting up close to that rock, you can hear music playing in the background. 

If you listen carefully, the song playing is a slowed down version of Rise of the Resistance by John Williams. Just an interesting easter egg.
