Working in electronic undertones mixed with classic orchestration brings into the show a sound that is luxurious yet unsettling.There is a remarkable change in mood from the quiet contemplation of "The Phoenix" to the full-blown tension of "Fine Leather," "The Shelter," "The Debt," and "Business Circus." "Broken Childhood" and "Rewind" are tales of personal loss and regret, while "Burn" amplifies the climactic emotional outbursts.The composers implemented this approach to make the isolation of the bunker audible. Every hum, every beat, and every note played on the violin echoed the fall of the character into moral ambiguity. The score runs for approximately 42 minutes and is digitally available on Spotify, Apple Music, and Amazon Music.Licensed tracks and their emotional weightThe licensed songs in Billionaire's Bunker make the show reach much farther emotionally than it would with the score alone."Lose Control"-The underground party sequence opens extravagantly thanks to Teddy Swims, revealing the chaos beneath a polished façade."Again (feat. XXXTENTACION)" by Noah Cyrus controls sorrow and confusion with repeats in flashback scenes."You Know I'm No Good" by Amy Winehouse plays during one of the moments of self-reckoning for one of the central characters."The Maze" by Manchester Orchestra underlines an important montage of inner turmoil.It is with "La calle del olvido – Los Secretos" that the finale closes, adding a nostalgic, almost haunting tone to the end of the series.At the same time, songs in the Spanish language, such as “Parte de Mí” by Nicki Nicole and “Un nuevo día brillará” by Luz Casal, not only preserve the cultural background of the show but also bring in a touch of lyrical sadness and genuineness.Why the music of Billionaire's Bunker worksIn the Billionaire's Bunker, music is not merely ambiance; it has the function of a storyteller. It gives rise to clear tensions even when words cannot and brilliantly reflects the characters' psychological states. The elegance of Mozart’s "Marriage of Figaro" is counterbalanced by deceit, while the sound of “Toxicity” and “The Debt” is full of moral decay.The selection of such diverse genres as classical to electronic, global pop to Spanish ballads, is intentional and indicates the main idea of the show: wealth that covers chaos with order.Streaming & availabilityThe soundtrack of Billionaire's Bunker was made available on September 19, 2025, under the Netflix Music label. As mentioned, it includes 21 original tracks by Lucas Peire & Frank Montasell; several licensed songs featured in the episodes were made available digitally across various platforms.The score can be heard on Spotify, Apple Music or Amazon Music; just look for it by the name of the album Billionaires' Bunker (Original Score from the Netflix Series).All through the scenes, the sound of the Billionaire's Bunker acts like an invisible narrator of the show, really expressing feelings when the poor characters cannot. The works of Lucas Peire not only have the skill of bringing out the feeling of isolation and mistrust, but also of bringing in the licensed songs that make the audience remember that there is a world outside the bunker walls.Also Read: Billionaires' Bunker Season 1 cast and character guide: Who plays whom in the upcoming Netflix thriller
