"3 Nights" revolves around Fike staying up late at a motel in the "City of Palms," otherwise known as Fort Myers, Florida, and the conversations and nude pictures he receives from a girl.
In a profile on Fike, The New Yorker said the parent EP of the song is "nostalgic for the early-two-thousands beach-bonfire style of Jack Johnson, with some of the watered-down reggae of 311 and the Red Hot Chili Peppers."
It further said "3 Nights" could "generously be classified as high-quality retail music", calling it "easy to listen to" and comparing it to "Rude" by Canadian reggae fusion band Magic!
[2] Matthew Strauss of Pitchfork gave the track a negative review; he described it as "absolutely harmless to a fault" and "neither soothing nor pleasant", further criticizing its lyrics as "mildly endearing but utterly forgettable".
[3] A music video directed by Nathan Rickard was released on April 4, 2019, and features Fike with friends in his hometown of Naples, Florida and Miami International Inn Motel, with a snippet of an unreleased song being played at the end.
