His favorite song - according to him - is Peggy Lee's cover of "Is That All There Is?"

Emphasis mine.

Is That All There Is?

Theme

The lyrics of this song are written from the point of view of a person who is disillusioned with events in life that are supposedly unique experiences. The singer tells of witnessing her family's house on fire when she was a little girl, seeing the circus, and falling in love for the first time. After each recital, she expresses her disappointment in the experience. She suggests that we "break out the booze and have a ball—if that's all there is," instead of worrying about life. She explains that she'll never kill herself either because she knows that death will be a disappointment as well. The verses of the song are spoken, rather than sung. Only the refrain of the song is sung. In most arrangements of the song, most notably in Peggy Lee's version, the music recalls the style of Kurt Weill, typified by songs such as "Alabama Song" and "Surabaya Johnny".

Whenever Trump says "never" - he's always lying. And he says he never drinks. His brother drank himself to death and Trump avoids mentioning him. I bet he hasn't mentioned his brother at all since he won in 2016.

It's a trip he says it's his favorite song. The page had a lot of edits since the last time I was there. This is from an old version.

Inspiration

The song was inspired by the 1896 story "Disillusionment" by Thomas Mann. Jerry Leiber's wife Gaby Rodgers (née Gabrielle Rosenberg) was born in Germany and lived in the Netherlands. She escaped ahead of the Nazis, settling in Hollywood where she had a brief film career. Rodgers introduced Leiber to the works of Thomas Mann. Most of the words used in the song's verses are taken verbatim from the narrator's words in Mann's story.
