TikTok plays a crucial role in shaping music trends today by providing a platform for songs to go viral and reach massive audiences quickly. The app's algorithm-driven content discovery system allows users to discover new music easily and share it with others through short video clips. Songs like "We Don't Talk About Bruno" from Encanto have gained immense popularity on TikTok due to their catchy hooks, engaging lyrics, and danceable beats. As users create challenges, dances, or lip-sync videos using these songs, they generate buzz around the music, leading to increased streams, downloads, and chart success.
