“They always have weird code names,” Comey told "PBS NewsHour." “It was ‘Sandcastles,’ and so I said ‘Beyoncé!’ And I was the only one in the room who had any idea what I was talking about. People were like ‘What?’ I said, ‘We built sandcastles’ — Honest to God, I sung like that.”

"Sandcastles" is the eighth track on Beyonce's sixth and most recent studio album, "Lemonade."

The ex-FBI chief says he also enjoys listening to Taylor Swift and Kendrick Lamar.

He added that he doesn't watch the high-tension espionage thrillers "Homeland" or "The Americans" on TV, preferring comfort viewing such as "This Is Us."

“Because look: Why do I need that stress?” he asked.

“It’s like, ‘I’m gonna die.’ Why do I need that? I get that all day long. But now that I’m totally zen, and don’t wear ties anymore, maybe I will get back to it,” he added.
