Biromba is a fascinating and somewhat mysterious word in this song. It doesn't have a direct, common translation in Spanish; it's used here as a playful, almost nonsensical sound or piece of gibberish.
In the context of the lyrics, it appears after the line "I was thinking 'bout you, No one else, no one else," suggesting a moment of being lost in thought, perhaps to the point of uttering random sounds or being so consumed by emotion that words lose their conventional meaning. It adds a unique, whimsical, and memorable element to the song, making it stand out.
This is a song about missing one particular person and not being able to think about anyone else. The singer keeps circling back to her, and the question he keeps asking is simply where she is now.
He talks about wanting to hold on to the affection he gave her, and about wounds that still genuinely hurt. Underneath the light, sunny sound there is real loss here. The Malibu of the title is a mood more than a place: an easy, golden style that he tells her suits her perfectly, and that he now associates with her.
In the chorus he runs through the names he has for her and ends up calling her his whole world. When they are together, he says, everything else disappears in a second. He remembers how suddenly it happened, the way she moves, and how he comforted her when she cried. By the end he is still asking the same question, which is what gives the song its ache.
Rusowsky is the stage name of Ruslan Mediavilla, a Spanish singer, songwriter and producer born in 1999 in Valladolid and raised in the Madrid area. He grew up in a musical family of Belarusian descent, started at his mother's music school at the age of four, and went on to study piano at a conservatory. The name comes from his nickname Rus and the character Wazowski from Monsters, Inc.
He began self-releasing tracks in 2019 and quickly became one of the most in-demand producers and collaborators in Spain's new alternative scene. His music sits somewhere between bedroom pop, R&B and electronic production, with Latin rhythms threaded through it, and it tends toward the melancholy: love, heartbreak, loneliness and a lot of introspection.
He signed to Warner Records in 2024 and released his debut album Daisy in 2025, which went to number one in Spain. For learners, his lyrics are a good way into everyday, informal Spanish, and he switches into English often enough that the two languages sit side by side.
