Crossover in music refers to a genre or style that blends elements from different musical traditions or genres, appealing to a broader audience. This can involve mixing genres like rock and pop, country and hip-hop, or classical and jazz. The goal is to create a sound that resonates with fans of both styles, often leading to greater commercial success. Crossover artists often gain popularity by reaching listeners who might not typically engage with a specific genre. For example, Lil Nas X's "Old Town Road" successfully combined country and rap, breaking records and sparking discussions about genre boundaries in the music industry.
