The soundtrack in general. Benjamin Wallfisch's score was able to capture the creepiness of the film, but was still able to show the innocence of the characters.
- "Every 27 Years
" plays over the logos and opening credits and sets the tone for this movie. And what better tone for It than Creepy Children Singing, immediately followed by a beautiful piano and string piece? - "Paper Boat" plays when Bill makes the paper boat and when Georgie sails said boat across the neighborhood, and it is beautiful. It starts off softly, but then the swelling orchestral score kicks in, and it fits the beautiful lighting, atmosphere, and cinematography perfectly; it also sounds adventurous, almost as if the movie itself is asking us, "You wanna go on an epic adventure? Who knows what might happen along the way?" But then the boat falls down the storm drain...
- "Georgie, Meet Pennywise" plays during Georgie's encounter with Pennywise and his tragic demise at the hands of the latter. It has a mysterious, creepy feel to it, which is the perfect orchestral introduction to the one and only Pennywise the Dancing Clown.
- Anthrax's cover of Trust's "Antisocial" accompanied the rock war between the Loser's Club and Bower's Gang. People were headbanging in the theater.
- "Deadlights" is one of It's most well-crafted pieces as it plays during the scene when Pennywise opens his mouth and reveals the Deadlights to Bev, complete with a pulsating overtone to start.
- "The Pennywise Dance" hilariously sets the mood for the movie's funniest moment, as a door crashes open and Pennywise stares down menacingly at Bev, captive in his lair...and starts dancing.
- If you want soft pieces, look no further than "Beverly" and "January Embers", which echo a bit of Thomas Newman.
- "Egg Boy", for being one helluva creepy track.
- "Shape Shifter". Stanley puts the creepy painting back on the wall and the chilling music starts, he realizes the woman from the painting isn't there. The door opens and a beautiful flute song starts playing. We think it's a part of the soundtrack. Then the flute drops...
- "Blood Oath" is a beautiful, melancholy track that plays during the last scene of the Losers Club all together, adding to the general bittersweetness of their goodbyes.
- "Kiss is a lovely track that closes out the film.
