Meaning of "Unstoppable" by Sia

The lyrics of "Unstoppable" by Sia delve into the theme of vulnerability and strength. The speaker starts by acknowledging their ability to deceive others with a smile, maintaining a facade until the evening. They refuse to show weakness, even when alone and crying. This reluctance is driven by fear, indicating that the speaker may have been hurt in the past or is afraid of being judged or rejected. The use of sunglasses to hide tears symbolizes the desire to protect oneself from being seen as fragile. The speaker acknowledges that expressing emotions is necessary for building deeper connections, but they are currently incapable of doing so due to their fear.

The phrase "I'll put my armor on, show you how strong I am" reflects the speaker's determination to demonstrate strength and resilience. By metaphorically donning armor, they aim to shield themselves from vulnerability and project an unbreakable image. The repetition of the line emphasizes their commitment to this defensive strategy. The references to being unstoppable, invincible, and powerful further emphasize the speaker's need to be seen as unassailable. They do not want to rely on external sources of strength, as stated in the line "I'm so confident, yeah, I'm unstoppable today." This suggests a desire for autonomy and self-sufficiency, as they do not want their confidence to be dependent on external validation or support.

Overall, "Unstoppable" explores the complex interplay between vulnerability and strength. While the speaker desires to maintain a tough exterior and hide their true emotions, there is a sense of inner conflict and yearning for authentic connections. The lyrics highlight the struggle between the fear of being hurt and the need for genuine emotional expression.
