* The [[http://www.youtube.com/watch?v=Dmp1sGsHOAg theme music]]. Performed [[http://www.youtube.com/watch?v=ZfmouyWcYLk live for your listening pleasure]].
* [[http://www.youtube.com/watch?v=uaUPDYXQUtw "Brothers in Arms"]], the time Charlie runs out in the rain with Bartlet's coat and the guitar kicks in. And the [[PowerWalk power walking]].
* Josh, Sam, CJ, and Toby welcoming Ainsley to the team with Gilbert and Sullivan posters and a rendition of [[http://www.youtube.com/watch?v=wd-0U3ZPENc "He is an Englishman"]].
* The military funeral of a homeless vet juxtaposed with [[http://www.youtube.com/watch?v=SXlPSXuJFDQ The Little Drummer Boy]]. ''TheWestWing'' was always fabulous with song juxtaposition.
* The lead-in to the theme tune in the episode "25", which was helped by brilliant cinematography. Bartlet finds out that [[spoiler:Zoey has been kidnapped]] and he immediately drops the photos of her he's been sorting and his glass of scotch. He then glances at Abbey, and as the background music crescendos, the camera zooms in on one of the pictures. The entire sequence takes twenty seconds, but it's a brilliant 20 seconds.
* [[http://www.youtube.com/watch?v=Q7H_L5cYkg8 The Jackal as performed by C.J.]]
* [[http://www.youtube.com/watch?v=DBh8gMlJZM8 The bit towards the end of "20 Hours in America, Part II"]], where the staff find out that a pipe bomb has been set off in a university sports facility and Bartlet gives a beautiful and moving speech written on the fly by Sam, and all accompanied by the Music/ToriAmos cover of "I Don't Like Mondays".
* The use of MassiveAttack's "Angel" at the end of "Commencement". It's the perfect balance of creepy, tense and trippy as Zoey realises she's been drugged and then her Secret Service detail realise she's missing, and the repetition of "Love you, love you, love you" as Amy questions Donna's feelings for Josh.
* The scene in "Noel" where Stanley pushes Josh to tell him how he really cut his hand and it's shown that music is making him relive the shooting. It's an amazing scene, if more than a little heartbreaking, and the music that helps make it so great?
-->'''Josh:''' It was the Bach G Major.
-->'''Stanley:''' Did he play it well?
-->'''Josh:''' [[IsTheAnswerToThisQuestionYes It was Yo-Yo Ma.]]
** Not to mention that Yo-Yo Ma insisted on playing the music live for every take rather than use a recording.
* Two amazingly fabulous pieces, set back-to-back and interlaced with scenes from a play the President is attending, in "Posse Comitatus" (season 3 finale):
** "[[http://www.youtube.com/watch?v=-tG9_vyXLhA Halleluja]]", sung by the late great Jeff Buckley [[spoiler:over the death of Secret Service Agent Simon Donovan.]]
** "[[http://www.youtube.com/watch?v=UTVtcZc8MGc England Arise]]", by the play's actors intercut with [[spoiler:the assassination of the terrorist (but Defense Minister of Qumar) Shareef by British forces.]]
