"4AM" is part of a batch of songs written in the wake of 2023’s acclaimed mixtape, Bubblegum. "4AM" lands alongside a visualiser and Episode 1 of a series of short films written by Biig Piig to accompany her forthcoming debut album.

Biig Piig describes "4AM" as “a song that I made with Zach Nahome about the after effects of a big night out. Even if you’re feeling isolated or alone, I wanted that chorus lyric to feel like an uplifting mantra you can say back to yourself. ‘4AM’ is a nostalgic feeling track that’s heavy: the verses are a reflection on the past and someone’s relationships with self, substances or partners. Starting with the lyrics “oh you could have hit me with the bad news first” is important as it cuts straight to the real feeling of it, and cuts out the glitz and glamour of a situation.”
