The song "Rule The World" by Christina Grimmie and Ryan Brown talks about the desire to have power and control over their own lives and the world around them. The lyrics describe the longing for wealth and fame, with references to having a billion dollars, rings on their hands, and living in a castle. They imagine themselves as unstoppable forces, ready to take over the world in a single night, feeling strong and guided by the light. The song also touches on the pressure and scrutiny that comes with fame, as they mention how people would be dying just to experience a moment of their fame. Despite this, they continue to chase their dreams and believe that they can achieve anything they want. However, towards the end of the song, there is a shift in tone. The lyrics mention getting lost in insanity and feeling disconnected from their true selves. The lines suggest the need to reflect on one's identity and remember who they really are. This could imply that despite the desires for power and fame, it's important to stay true to oneself and not get consumed by external influences. Overall, "Rule The World" explores themes of ambition, power, and the desire for control, but also hints at the importance of self-discovery and staying grounded amidst fame and success.
