What Does “락 (樂) (LALALALA)” Mean?

LALALALA is a stadium-sized declaration of persistence and self-belief, built around the irresistible momentum of its repeated hook. The song channels classic rock energy — loud, uncompromising, and unapologetically big — to communicate that Stray Kids will keep going no matter what obstacles arise. The wordless 'LALALALA' refrain functions as a universal language of defiant joy.
