Smash is an American musical-drama television series created by playwright Theresa Rebeck. It premiered in the United States on NBC on February 6, 2012. The series revolves around a fictional New York theater community making new Broadway musicals. In the first season, the focus was on the making of Bombshell, a musical based on the life of Marilyn Monroe. In the second season, the show was split between taking Bombshell to Broadway and the creation and mounting of a contemporary pop musical called Hit List that was about the price of fame. Other fictional musicals that were touched on for which original songs were performed include Beautiful and Liaisons. A few of the songs were written for events outside of the aforementioned musicals.

Marc Shaiman and Scott Wittman wrote all but one of the songs in the first season. In the second season, they wrote all of the songs outside of Hit List, along with several Hit List songs, as will be noted below. All their songs written for the show, except for a couple where only a few lines were written, can be found listed in the ASCAP music database. The other songwriters are noted and referenced where appropriate.

The following list details the original songs featured in Smash.

It was written by Marc Shaiman and Scott Wittman, but in the show's universe, it was written by songwriting team Tom Levitt (Christian Borle) and Julia Houston (Debra Messing) for their Marilyn Monroe musical Bombshell.

In the episode, Karen Cartwright (Katharine McPhee) needs to give a dance audition for the producing team as part of trying to get the role of Marilyn in Bombshell. She works with director and choreographer Derek Wills (Jack Davenport) and then performs this song with the ensemble members in front of the producing team.

The song is reprised several more times during the first season. It is performed by Ivy Lynn (Megan Hilty) in the fourth episode "The Cost of Art", by Karen and Ivy separately in the seventh episode "The Workshop, and by Karen in the fifteenth episode "Bombshell" for a preview show in Boston.

It was written by Marc Shaiman and Scott Wittman, but within the show's universe, it was written by an unnamed composer for the Liaisons musical that Ivy Lynn (Megan Hilty) is in.

In the episode, Ivy is unhappy with the direction that the Liaisons production has taken now that star Terry Falls (Sean Hayes) has gone off his various medications and has turned the show into a trainwreck. With the press in attendance to get a preview of the show, she sings this song in an operatic and comedic way, stealing some of Terry's thunder.

A Thousand and One Nights

"A Thousand and One Nights" is an original song introduced in the twelfth episode of the first season of the musical TV series Smash, entitled "Publicity". It was written by Marc Shaiman and Scott Wittman, but in the episode, it is presented as a character's fantasy of a Bollywood musical number so the songwriter is unnamed.

In the episode, Karen Cartwright (Katharine McPhee) and her boyfriend Dev (Raza Jaffrey) are having a tense dinner with movie star Rebecca Duvall (Uma Thurman) at an Indian restaurant. Rebecca has taken over as the lead in the Marilyn Monroe musical Bombshell, while Karen is her understudy. However, Rebecca has taken Karen out for quite a bit of partying, which has caused tensions between Karen and Dev. During the meal, Rebecca and Dev start to argue about who is the one harming Karen. An uncomfortable Karen starts watching a Bollywood movie on one of the screens, and then imagines herself in a Bollywood-style movie with first Dev, then herself singing the song, with practically the entire rest of the main cast and various supporting players of the series performing as backup. The song is sung in the style of an Indian Bollywood song, with the performers dressed in Indian clothes.

Arthur Miller Melody "Arthur Miller Melody" is an original song introduced in the ninth episode of the first season of the musical TV series Smash, entitled "Hell on Earth". It was written by Marc Shaiman and Scott Wittman.

In the episode, Julia's husband Frank (Brian d'Arcy James) is rummaging around his wife's nightstand looking for something and comes across the sheet music. Something about it catches his eye. Julia later comes home and Frank is at the piano with the sheet music and quietly playing and singing a little bit of the song ("Arthur Miller Melody" is written at the top of the sheet music). He stops and asks her about it, saying the lyrics about Marilyn on the Brooklyn Bridge sound a little strange, voicing his suspicion that Julia is having an affair and the lyrics are really about that. Julia breaks down and admits that she was having an affair, but it is over.

By season 2, the song has developed into a solo sung by Arthur Miller, entitled "The Right Regrets". It was performed by Tom and Julia in Episode 15, The Transfer. The song is available on the cast album Bombshell.

At Your Feet "At Your Feet" is an original song introduced in the fourteenth episode of the second season of the musical TV series Smash, entitled "The Phenomenon".

In the episode, we get a short segment of the song, with Leigh Conroy (Bernadette Peters) as Marilyn Monroe's mom Gladys taking young Marilyn (Sophia Anne Caruso) to Grauman's Chinese Theatre and the two perform the song. Earlier, Tom had indicated to Kyle Bishop (Andy Mientus) that Marilyn's mom had left her at the theater and so it was a sad moment, but Kyle suggests that maybe they make the number a happy one, changing what really happened in Marilyn's life to something that was more fantasy. After Kyle's death, we see the number performed during a Bombshell show as more of a happy fantasy than the sad way it was done previously.

The song is available on the cast album Bombshell.

Big Finish "Big Finish" is an original song introduced in the seventeenth episode of the second season of the musical TV series Smash, entitled "The Tonys".

Karen overhears Jimmy singing the song on a piano and then moves closer to watch him perform it.
