Airplane song

An airplane song is a song that would sound really good to listen to on a plane. These songs have a nostalgic vibe (regardless of the age or relevance of the song) and feel memorable and free-flowing. They also have a nighttime vibe. They are neither super upbeat nor a sad ballad. Surprisingly, many popular pop songs go under this category. Some well-known examples include:

Style by Taylor Swift (and also half of that album)
Streets by Doja Cat
Ridin Solo by Jason Derulo
Cooler Than Me by Mike Posner
Into You by Ariana Grande
Attention by Charlie Puth
Be The One by Dua Lipa
I Feel it Coming by The Weeknd
Lost by Frank Ocean
Who Knew by P!nk
Wide Awake by Katy Perry(she has very many of these!)

Half of Katy Perry's discography is upbeat songs while the other half is Airplane Songs.
