Significance: This is significant because it shows that Daisy left Tom over Gatsby and the song represents Fitzeragald's theme of the corrupt and crushed American dream. Gatsby didn't end up with the love of his life and the song is talking about how in love the couple in the song is which is ironic, displaying his crushed dream.
How it affects the mood of the book: This affects the mood of the book because it portrays to the reader that not everything in their fancy life is perfect and it transforms the mood to disappointment. In almost every love story, Gatsby would have ended up with Daisy. However, in this book they do not end up together creating the mood of corruption and reality of the American Dream
Video/Audio:

Context: Gatsby had waited up all night in front of Daisy's house hopping she would come out, but she never did. He told Nick about how they had met and how she had chosen to marry Tom. 
Significance: This is a turning point in Gatsby and Daisy's realtionship because there is no longer a hope for the two to be together in the future. The song shows Gatsby's feelings toward life now. He is upset that he didn't get what he wanted and doesn't want anything to do with the society what so ever.  
How it affects the mood of the book: This affects the mood of the book because now the reader has no hope  for Gatsby and Daisy. The song shows a different outlook on the society and how it changes people and how it is not all that and a bag of chips. The reader is now starting to see all of the negative things about this society and the song furthered the idea of corruption.

Ooh, she got it all planned out
Yeah, I can see it all right now

I'll wear my black suit, black tie, hide out in the back
I'll do a strong shot of whiskey straight out the flask
I'll try to make it through without crying so nobody sees
Yeah, she wanna get married
But she don't wanna marry me

I remember the night when I almost kissed her
Yeah, I kinda freaked out, we'd been friends for forever  
And I always wondered if she felt the same way
When I got the invite, I knew it was too late

How it connects to the mood of the story:
This song can directly relate to the mood of the book. This song is about a guy who has been best freinds with this girl for a long time. He falls in love with her but by the time he wants to do something about it its too late because she is getting married to someone else. Even though "Three O'clock in the Morning" is about a couple who are deeply in love, the message portrayed in the story is the same. The song is ironically played to display disappointment in the idea that Daisy left the party with Tom. The song "Marry Me" conveys the exact same message. The Gatsby is realizing he was too late and that Daisy married someone else. Overall, "Marry Me" conveys the idea of a disappointment with a love.

Well, I've been afraid of changin'
'Cause I've built my life around you
But time makes you bolder
Even children get older
And I'm getting older, too

Well, I've been afraid of changin'
'Cause I've built my life around you
But time makes you bolder
Even children get older
And I'm getting older, too
Oh, I'm getting older, too

I took my love, I took it down
I climbed a mountain and I turned around
And if you see my reflection in the snow covered hills
Well the landslide will bring it down
And if you see my reflection in the snow covered hills
Well the landslide will bring it down
Oh, the landslide will bring it down

How it connects to the mood of the story:
This song is about a girl who devoted her life to this man who she thought she loved deeply, however he cheated on her. This can relate to Gatsby because he devoted his life to Daisy and reconnecting with her, and it never really happened. "Beal Street Blues" is about someone describing a place that seemed to be great as a place that is terrible and full of sin and heartbreak. The person also says that he will never willingly go there. The song portrays  Gatsby's feelings after Daisy did not come outside the house. Although the meaning of the two songs are different, the same mood is portrayed. In "Beal Street Blues", it sets the mood that Gatsby is fed up with the place that keeps leaving him disappointed and crushed. "Landslide" also potrays the mood that the girl is fed up with what she revolved her life around and won't go back.
