Vriller literally means "to drill" or "to spin like a drill". However, in modern French slang, it's often used to mean "to go crazy," "to lose it," or "to spiral out of control."
In the context of the song, the artist sings "Réapprendre à vriller" (Relearn to go crazy/spiral). This suggests a desire to reclaim a wilder, less controlled part of herself, perhaps as a way to cope with heartbreak or to rediscover a lost sense of self after a difficult relationship. It's an intriguing and less common usage that adds depth to the lyrics.
“À La Folie” is a vibrant pop confession where French singer Adèle Castillon turns the volume up on heartbreak, letting us feel every neon-lit tear of a love gone wrong. Over a pulsing beat, she admits she has “spent too much time drowning in tears” and now feels unarmed, her inexperienced heart caught between FOMO and slow-motion memories that have frayed beyond repair. The repeated vow to monter la sono (crank up the speakers) becomes her battle plan: drown out the past, talk only to her piano, and dance through the night until she forgets the ties that once bound her. “À la folie” usually means loving someone “madly,” yet here it flips into a portrait of emotional madness—obsessively replaying flaws to finally break free. The song’s mix of English hooks and French vulnerability makes the story feel universal: when love burns too hot, the only remedy is to blast your favorite tracks, let the bass shake loose the pain, and learn to love yourself all over again.
Adèle Castillon was born in 2001 in Angers and grew up between theater and a YouTube channel she started as a young teenager, where her comedic videos about beauty culture racked up millions of views. She moved into acting as a teenager, appearing opposite Gilles Lellouche and Louise Bourgoin in the 2017 film "Sous le même toit," and at fifteen she traveled to Dharamshala to interview the Dalai Lama.
Music came next: at seventeen, in Nantes, she and Matthieu Reynaud formed the duo Videoclub, whose 80s-tinted single "Amour plastique" turned into a global viral hit before the pair split in 2021. She has since built a solo career on Columbia Records, releasing the album "PRD: Plaisir Risque Dépendance" in 2023 and "Crèvecœur" in 2025, carried the Olympic torch for the Paris 2024 Games, and has played major French festivals including Les Vieilles Charrues.
