One good thing about rewatching all the episodes is that I have discovered a lot of great songs. I had no idea how the makers had incorporated some really good music into the show all to great effect. I have posted some of my favourites with links to YouTube clips showing where in the show the music was used, that is, where I first heard the music. The following list represents my postings from the past couple of weeks showing the music video for the song with complete lyrics plus references about the song, the album and the artist. And I mention in which episode of Castle the song was used.

Amp Fiddler: If I Don't
What a fabulous song and the original music video for the song is just quite original. Ya gotta see it! – This was used in season 1, episode 4, "Hell Hath No Fury" at the very end of the show when Beckett gets angry at Castle about his choice of name for the female detective he's going to write about based on Beckett.
Beckett: What kind of a name is Nikki Heat?
Castle: A cop name.
Beckett: It's a stripper name.
Castle: Well, I told you she was kind of slutty.

Colbie Caillat: Fallin' For You
My discovery of this song did not come from the show itself but from a fan video. Somebody put together clips from the series showing this on-going romance between the show's protagonists along with the music. I thought it made a good montage.

Bitter:Sweet: Get What I Want
In season 1 episode 9 called "Little Girl Lost", an old flame of Beckett's shows up and stirs the pot with Castle and Beckett. The clip (you're a mysterious woman – castle 1x09) shows the very end of the episode when Beckett announces she has a date but does not give any details. When Castle is intrigued by her reticence, she replies, "Maybe there's more of Nikki Heat in me than you think." This song by Bitter:Sweet is the fade out and perfectly captures the feeling of the moment.

The Daylights: I Hope This Gets To You
This song has an interesting story to itself. The composer posted this on YouTube wanting to see how long it would take for his girlfriend to run across it. Apparently it took 48 hours.

In season 3 episode 9 called "Law & Murder", Castle pretends he has never seen the movie Forbidden Planet to trick Beckett into taking him to the movies, an unofficial date. The clip (Castle Beckett 3x19 "That's it, I'm taking you") shows the two of them getting on the elevator with this song playing in the background. It certainly captures the hope of something happening between us and the hope that message gets to you.

Golden State: Love Song
In season 2 episode 12 "A Rose for Everafter", Castle runs into a former girlfriend played by Alyssa Milano. Beckett may be jealous but it turns out there's nothing to worry about; Castle and former part friends. The final scene, though, has former leaving the precinct and saying to Beckett, "He's all yours now". This telling moment in this on-going cat and mouse between the two protagonists of the show is nicely accompanied by this song.

OneRepublic: Stop And Stare
In season 1 episode 1 called "Flowers From Your Grave", we have the very first episode of the television series which introduced our cast of characters and the comedic and romantic interplay between crime novelist Richard Castle and New York Detective Kate Beckett. The end of the show has this sexually and romantically charged scene between Castle and Beckett that sets the viewer up for the rest of the series. Now tell me how you could in any way not tune in next week, the week after that, and now for the fourth year to see the build-up of one of the greatest (longest?) romances in primetime TV?

Lady Antebellum: Need You Now
This a fan video of various romantic scenes between the show's protagonists set to music. It captures the heartache of longing for somebody you're not sure you're ever going to get. Hey, is that an apt description of this on-going game of cat and mouse between Castle and Beckett?

Lex Land: My Fault, Your Mistake
In season 2, episode 1, Deep in Death, the final scene of the show has a fight between our two love birds. Castle mistakenly thinks he can win points with Beckett by re-opening the murder of Beckett's mother. His enthusiastic presentation of his ideas about the case is met with anger from Beckett who explains how she had tried so hard to drop her own obsession about the unsolved murder. In a conversation with his own daughter, Castle comes to realize his error and apologizes to Beckett. This song by Lex Land plays out at the end.

Sara Jackson-Holman: Into The Blue
In season 2, episode 24, Deep in Death, the final scene of this season finale has Beckett realizing she shouldn't hesitate to tell Castle how she feels about him. In fact, these feelings are so strong, she dumps her boyfriend.

However, romance demands tension and tension we get. Just as Beckett is about to spill her guts, Castle's ex-wife shows up and we all discover Castle is going away with her, the ex-wife. What? Congrats to the actress Stana Katic for portraying Beckett's confusion, disappointment or sense of loss. Geesh, imagine you're at the point of declaring your feelings for somebody and they announce they're running off with somebody else?

Just as an aside, this makes for a sad season two finale but makes for a great season three opener.

Il Divo: Caruso
This is another fan video, clips from the Castle show set to music. What a great song, though and what a story. Il Divo ("divine male performer" in Italian) is a multinational operatic pop vocal group created by music manager, executive, and reality TV star Simon Cowell.

Jules Larson: You Know It's True
In season 3, episode 5, Anatomy of a Murder, this clip has Martha, Castle's mother saying getting somebody out of prison is a sign of true love. At the very end of the show, Castle presents a hypothetical situation where he is in jail and Beckett says she would get him out. Obviously this is interpreted by Castle as a sign of true love. For us, the viewers, we just sit in front of the TV screaming, "You dummies! You love each other! Admit it!"

Colbie Caillat: I Do
A fan video using this song to highlight the Caskett romance. Geesh, have I become gaga about this television romance?

Jason Mraz: Lucky (with Colbie Caillat)
Another fan video using this song to highlight the Caskett romance. Caskett? The author of the video uses the term "Stanathan". Ha!
