The lyrics to Kylie Minogue's song "Can't Get You Out of My Head" express the idea of being completely consumed by love for someone. The repetition of the opening lines "La-la-la-la-la-la-la-la" creates a hypnotic effect, reinforcing the idea that the singer's thoughts are completely consumed by the subject of the song. The verses express the obsessive nature of the singer's thoughts, as she can't help but think about this person constantly, day and night.

The chorus repeats the phrase "I just can't get you out of my head" twice, emphasizing the repetition of the singer's thoughts. The second line of the chorus, "boy, your lovin' is all I think about," implies that this love is all-consuming and that the singer is completely under the spell of the person she is singing about.

The bridge of the song adds a layer of complexity to the lyrics, as the singer sings about a "dark secret" and the fear of being abandoned by the person she loves. The lines "Don't leave me left in your heart / Set me free / Feel the need in me / Set me free" create a sense of desperation, as the singer begs her lover not to abandon her. Overall, the lyrics to "Can't Get You Out of My Head" express the dizzying intensity of love, both in its all-consuming nature and its potential for fear and vulnerability.
