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.
