Secrets and mysteries aren't the only thing you can count on each week from Pretty Little Liars.

There's also the show's song selection, which always seems to fit well with every scene, doesn't it? Each week, we update our Pretty Little Liars music section with a sampling from each episode.

For example, the following singles were played in "If at First You Don't Succeed, Lie, Lie Again."

• Katie Herzig - "Hey Na Na"
• Allie Moss - "Leave It All Behind"
• Amy Stroup - "Redeeming Love"
• Brooke Waggoner - "Heal For The Honey"
