Metal Gear Solid Phantom Pain easter egg! **MINOR SPOILER**

So I just found a mission that has a radio in a tent, playing what the radio in P.T. was playing. Unfortunately it didn't look like I was able to take a cassette from the radio, so don't plan on playing the description of the murders on repeat. I think it happened in Mission 19 or 20, I can't quite remember. But the tent is in the woods, on a fairly narrow path that you have to go down.
