Before 2020, rap music in Vietnam was largely an underground phenomenon. While it had a passionate and dedicated following, the genre was often misunderstood by the general public. It was frequently associated with street culture and sometimes viewed with skepticism, remaining on the fringes of the mainstream music industry. For most Vietnamese families, rap was not the music you would hear on prime-time television or on major radio stations. It thrived in small clubs and online communities, a vibrant but niche part of the country's cultural landscape.

Everything changed with the broadcast of 'Rap Việt'. This television show, modeled after global talent competition formats, presented rap music in a completely new light. With a panel of famous, well-respected coaches and high production values, the show gave rap a polished, professional stage. The competitive battles were exciting, but the quality of the music and lyrics featured prominently in every episode. 'Rap Việt' shattered viewership records, proving that a massive audience was not only ready for rap but enthusiastic about it. The show transformed the genre from a subculture into a national sensation almost overnight.

The impact of 'Rap Việt' was immediate and far-reaching. Contestants like Dế Choắt and GDucky, who were previously known only within the underground scene, became household names. Their songs topped the charts, and they were suddenly among the most in-demand artists in the country. This success went beyond individual fame. Suddenly, rap music was everywhere – in television commercials, on popular talk shows, and collaborating with pop stars. The show effectively built a bridge between the underground and the mainstream, making the genre accessible and appealing to a much wider demographic, including parents and even grandparents.

But what was the secret to its phenomenal success? It wasn't just the catchy beats or clever wordplay. 'Rap Việt' succeeded because it focused on storytelling. The show delved into the personal journeys of the artists, sharing their struggles, dreams, and triumphs. This humanized the rappers, allowing millions of viewers to connect with them on an emotional level. Audiences saw the passion and hard work behind the music, which helped to dismantle old prejudices. They weren't just listening to songs; they were rooting for people they felt they knew.

In conclusion, 'Rap Việt' did more than just create a few music stars; it legitimized an entire art form in the eyes of the Vietnamese public.
