The result was Romance, an album that reinterprets twelve boleros, whose original versions date from between 1944 and 1986. The impact of these new interpretations was immediate. Singles like "Inolvidable" and "No sé tú" climbed to the top of the Billboard Hot Latin Songs chart in the United States and remained at the top of the Mexican charts for a considerable period of six months. Other tracks like "Mucho corazón" and "Cómo" also reached prominent positions on Hot Latin Songs, while "Usted" and "La barca" received extensive radio play in Latin America. The album's promotion included a tour of the United States and the American continent. Music critics praised Luis Miguel's vocal quality and the album's meticulous production.
Romance was not only a critical success but also a commercial phenomenon. It is estimated to have sold over 8 million copies worldwide. In the United States, the album remained at number one on the Billboard Latin Pop Albums chart for thirty-two weeks. It was a milestone, being the first Spanish-language album, without genre fusions, by a Latin artist to receive a gold record from the Recording Industry Association of America (RIAA). This recognition extended to Brazil and Taiwan, setting a precedent for a Spanish-speaking singer. In Argentina, it became the best-selling album by a non-national artist. The album is widely credited with revitalizing the bolero genre, inspiring other artists such as Daniela Romo and Charlie Zaa to record their own versions of boleros. The success of Romance laid the groundwork for Luis Miguel to later release three more albums dedicated to this genre: Segundo romance (1994), Romances (1997), and Mis romances (2001).
