Siempre Tuya Desde La Raíz

"Siempre Tuya Desde La Raíz" (English: Open Up Your Heart) is a song recorded by Mexican singer Paulina Rubio, taken from her forth studio album Planeta Paulina (1996). It was released as the album's lead single in July 1996, by EMI Latin. The track was written by Karla Aponte and the music by Cesar Lemos and Rodolfo Castillo, whilst production was handled by Marco Flores. It was recorded in Miami, Florida at South Beach Studios during spring 1996. Musically, it is a dance-pop song that incorporates elements of techno, house, disco, and electronic keyboard instrumentation, whilst the lyrical content talks about Rubio's seduction with sexual metaphors.

Upon its release, "Siempre Tuya Desde La Raíz" received critical acclaim from music critics. Several critics selected the track as a standout from many of her records and compilation, whilst individual reviews commended the production and influence of dance and house elements. An accompanying music video was directed by Fernando de Garay with a concept cosmic "and 70's dance." It was choreographed by Miguel Sahagún.

In 2016, the website UniversoGay includes the song among the "15 best songs to enjoy submission, in Spanish", highlighting the sexual lyrics metaphors.
