"Extranjera" marks a significant milestone in Dulce María's music career, showcasing her growth as an artist. The album features 12 tracks, including the hit single "Extranjera", which shares the same title as the album. The music style of this album blends pop, rock, and electronic elements, reflecting Dulce María's evolution as a singer.
In 2010, Dulce María was part of the Mexican pop group "Dulce María" (also known as "Dulce María y su grupo") but more information about her music is related to her work as part of the group "RBD" (Rebelde) which she was part of from 2004-2006.
The album is a cohesive "coming-of-age" project that distances Dulce María from the polished group sound of RBD, leaning instead into more personal and edgy pop-rock influences.
