The song "I Believe in You" by Kacy Hill is about finding hope and support in someone else during tough times. The lyrics suggest that the speaker has been struggling to achieve their goals and dreams, but feels comforted and inspired by the belief that the person they love has in them. The chorus repeats the phrase "I believe in you" as a reminder of this support, and a declaration of faith in their abilities. The verses touch on themes of self-doubt and the pressure to be successful, with lines like "I waited on a kiss, from the sky, but it won't touch me" and "I wanted for the world, to love me more". However, the song ultimately suggests that external validation is not necessary for happiness, and that the most important thing is the support and love of those around us. The bridge features a spoken word section from Francis and the Lights, which touches on the theme of selling out or compromising one's values in pursuit of success. Overall, "I Believe in You" is an uplifting track that celebrates the power of love and support in overcoming adversity.
