It's saying something when even people who don't like the films have praised the soundtrack and score as being incredible. The soundtrack is generally an awesome mix of indie rock, alternative rock and pop rock by various artists, while the score was composed by the award-nominated-and-winning Carter Burwell (Twilight and Breaking Dawn Parts 1 and 2), Alexandre Desplat (New Moon) and Howard Shore (Eclipse).
- "Flightless Bird, American Mouth" by Iron & Wine. This is one of the prettiest songs on all the Twilight soundtracks. While the lyrics are definitely strange, the melody and tune of the song is beautiful. There's even a reprise in the 4th movie!
- "Let Me Sign" by Robert Pattinson (singing starts at 0:48). Rob's gravely voice is very interesting. Fun fact: Nikki Reed ("Rosalie") secretly recorded Rob singing this and gave it to director Catherine Hardwicke. They played Bella's "death" scene over and over again with a bunch of different songs, and this one fit the best.
- "Bella's Lullaby" from the score. Carter Burwell had to compose something that in the books was this big romantic, lovely piece, and he managed to exceed most expectations.
- "Supermassive Black Hole" by Muse. Though it's hasn't got much to do lyrically with the scene in question (the Cullens playing baseball), it's still a great song and made the scene just a tad more awesome. Also worth noting that Stephenie Meyer likely had an influence here, Muse being one of her favourite bands.
- Decode by Paramore, which plays over the end credits. It was written specifically for Twilight (and even includes clips of the film in the music video) and many people feel it perfectly encapsulates the films story and Bellas feelings towards finding out the truth about Edward, though its also a great song in its own right. It also makes it well worth sitting through the credits even if you didn't much care for the film.
- Eyes on Fire by Blue Foundation has over 35 million plays on Youtube. Maybe its a case of Song Association, maybe its because its just a damn good song and maybe its a mix of both. As with "Decode", it can easily be interpreted as Bella's feelings of frustration over Edward's secretive nature and strange behaviour - indeed, it plays over the scene where Bella returns to school intending to confront Edward for being a Jerkass to her in their first class together, only to find he's disappeared for a whole week, essentially kickstarting Bella's quest to find out the truth about him.
- "Phascination Phase" is a lovely track that rather nicely portrays the feeling of someone sparking your interest and wanting to know more about them.
- "Hearing Damage" by Thom Yorke. A cool techno-pop song that isn't Dubstep. The lyrics ("In my eyes/ You can do no wrong") fit really well for the movie.
- "Possibility" by Lykke Li. Played during Bella's depression, this song is hauntingly slow and fragile, showing the delicacy of Bella's mind and emotions.
- "A White Demon Love Song" by The Killers is an alt-rock song that perfectly sums up the book's premise. Of course, the "white demon" is Edward; "widen your heart's scope" is referring to Bella, telling her to love Jacob and be happy with a (more) normal boyfriend, to open her heart to a new love; "who let your friends go?" is nodding to Bella's lack of human friends for the first few months post-Edward; "let us be in love" means that Edward and Bella's relationship is controversial and that they just want to be together, without any complications or danger; "let's do old and gray" is a bit obvious, but captures Jacob's desire to be with Bella until they age and die, something she could never have with Edward; "white demon, where's your selfish kiss?" is talking about Edward and his vampire bite. Jacob wonders if Edward would bite and kill Bella due to his own bloodlust.
- "Slow Life" by Grizzly Bear, feat. Victoria Legrand. Only a small section of the song is played during the scene where Bella almost drowns and sees Edward's 'ghost', but it's still very effective (the full song is well worth a listen too). The lyrics of the song ("Even though you're the only one I see/It's the last catastrophe/Place your bets on chance and apathy") encapsulate Bella's feelings around Edward in the scene, and by extension the rest of the film, quite well.
- "What Part Of Forever" by Cee Lo Green, an old school soul-pop jam that perfectly encapsulates Jacob's character, and surprisingly upbeat sounding considering the franchise's regular musical outings.
- "My Love" by Sia. It's an absolutely beautiful and poignant love song, that managed to create a suitably romantic and emotional atmosphere for when Edward proposes to Bella.
Breaking Dawn: Part 1:
- "A Thousand Years" by Christina Perri. Composed for Twilight, this is the kind of simple pretty song that could be used for almost any love story, romantic, familial, or otherwise. There's even a reprise in the sequel!
- "It Will Rain" by Bruno Mars is a sad (if a bit wangsty at times) song about heartbreak and its various stages.
- "Cold" by Aqualung and Lucy Schwartz is a hauntingly sad song that easily emotes the feelings of despair and helplessness Edward and Bella initially feel during her pregnancy.
Breaking Dawn: Part 2:
- "Renesmee's Lullaby / Something Terrible". It starts out as a similar tune to "Bella's Lullaby", a calming, almost whimsical piano piece, then near the end shifts into something much darker and more dramatic complete with a choir and a tolling bell, ending on a positively sinister note for a track with "Lullaby" in the title. It perfectly reflects the protagonists' arc in the final film; at the beginning everything is relatively idyllic, with Bella and the Cullens finally getting their happily ever after, only for the growing threat of the Volturi to encroach on their peaceful lives, with the increasing fear that not all of them - if any - will make it out alive.
- "Where I Come From" by Passion Pit is a very uplifting-sounding song, which plays when Bella awakens as a vampire and sees the world for the first time with her new abilities. It helps add a sense of wonderment to the scene, and its lyrics about staying positive and not letting bad things "destroy these dreams" seem quite fitting with Bella's new state of being after all the horror that occurred in the previous film.
