The Waterford House Burns (The Handmaid's Tale)
This is one listing that's a blend of score and music. Serena Joy set the house on fire on The Handmaid's Tale Season 3 Episode 1, "Night," and the quiet, haunting scenes are beautifully accompanied by a score. Serena Joy, June, and the rest of the house's occupants exit, June's voiceover plays and then as the house crumbles "I Don't Like Mondays" by The Boomtown Rats blasts.
Villanelle Shoots Eve (Killing Eve)
The end of Killing Eve Season 2 Episode 8, "You're Mine," used a song that viewers have heard before. After Villanelle pulls the trigger and leaves Eve amongst the Roman ruins she exits to "Sigh" by Unloved. The haunting lyrics perfectly accentuate what just happened and strengthen the mood of the final scene of the finale.
The Final Supercut (Timeless)
At the end of the Timeless movie, there was one-time travel thread to close. In order for the timeline to be maintained, Lucy had to go to the bar in Sao Paulo, Brazil and give Flynn her journal. The meeting causes Flynn to go to Mason Industries and steal The Mothership, beginning the series. (I know, time travel right?) As clips of the series proper play, it's scored over a cover of Cyndi Lauper's "Time After Time" by Joseph William Morgan providing the perfect ending to the time travel series.
The Returnees Venture Out Into the World (The 4400)
You'll have to do some digging to watch this one. When The 4400 premiered in 2004, the pilot featured a montage scene when the returnees reentered society set to Ivy's "Worry About You." The melancholic tone of the song and the sentiment of the lyrics were the perfect compliment to the returnees' experiences as they tried to explore a world that was now foreign to them.
The Walk to the Elevator (Grey's Anatomy)
Grey's Anatomy Season 15 Episode 19, "Silent All These Years," is an emotionally powerful episode, but there is one pivotal scene as they take a patient to surgery. The hallway lined with women as Jo and Teddy take their patient to the elevator is made that much more moving by the choice of "Lost Without You" by Freya as the accompanying music.
Racing to Stop Walter Sykes (Warehouse 13)
During Warehouse 13 Season 3 Episode 11, "Emily Lake," the team finds out that a new member who they thought betrayed them is actually undercover. While Track and Field's cover of "Running Up That Hill" plays they race to a hanger where Walter Sykes is getting ready to enter his endgame, but miss the plane and find Steve's body in the hanger instead. It's a tense moment that's heightened by the sublime tones of the song and the lyrics perfectly synced to different moments in the montage.
