The song "90210" by Travis Scott and Kacy Hill tells the story of someone who has worked hard to become successful and is now enjoying the luxuries and rewards of their success. The term "90210" refers to the postal code for Beverly Hills, which is a city known for its wealth and glamorous lifestyle. The narrator is addressing their family, friends, and former doubters, explaining how they used to take the "long way home" -- referring to their hard work and dedication -- and now they have achieved their goals and are living a life of financial comfort, surrounded by beautiful things. The chorus of the song, performed by Kacy Hill, speaks to the narrator's attachment to the feeling of accomplishment and wealth, which has now become an addiction.
