Castle Music: What's the Song That Played in Season 4, Episode 11?

Castle's music supervisors have a knack for picking just the right songs to play in each episode, and in Season 4, Episode 11, "Till Death Do Us Part," they hit it out of the park again.

Though there was only one song featured, "Bolero," it was pitch-perfect! As a character noted, "'Bolero' increases the chance of closing the deal by 12 percent."

Song: "Bolero" by Andrew Previn and the London Symphony Orchestra
