Their melody is extremely similar in some parts and Lana said 'Young & Beautiful' was supposed to go to the Paradise LP, but she then gave the song to the producers of The Great Gatsby re-writing the song in it's entirely.
I seriously feel the absent soul of 'Young & Beautiful' in 'Old Money'
What do YOU think?
Update: To add more fire to the topic
the second verse of Old Money goes like this OMG:
The power of youth is on my mind,
Sunsets, small town, I'm out of time
Will you still love me when I shine?
From words but not from beauty
