La Bamba (song)
"La Bamba" has been covered by numerous artists, most notably by Los Lobos, whose version was the title track of the 1987 film "La Bamba" and reached No. 1 in the U.S. and UK singles charts in the same year.
La Bamba (song)
"La Bamba" is a classic example of the "son jarocho" musical style, which originated in the Mexican state of Veracruz and combines Spanish, indigenous, and African musical elements. The song is typically played on one or two Arpa jarochas (harps) along with guitar relatives the jarana jarocha and the requinto jarocho' Lyrics to the song vary greatly, as performers often improvise verses while performing. However, versions such as those by musical groups Mariachi Vargas de Tecalitlan and Los Pregoneros del Puerto have survived because of the artists' popularity. The traditional aspect of "La Bamba" lies in the tune, which remains almost the same through most versions. The name of the dance, which has no direct English translation, is presumably connected with the Spanish verb "bambolear", meaning "to shake" or perhaps "to stomp". Or the name may perhaps be derived from the Kimbundu word "mbamba" meaning "master" as in someone who does something adeptly or skillfully. 
Selena singles discography
American singer Selena released twenty-four official singles, seven promotional singles. Her career began as the lead vocalist of Los Dinos in 1980. Her albums with Los Dinos on indie labels failed to achieve any chart success. In 1987, her remake of Ritchie Valens' "La Bamba" peaked at number 19 on the United States "Billboard" Hot Latin Songs chart, her first entry. She signed with EMI Latin nine years later as a solo artist though her band continued to tour with her. Selena appeared on "Buenos Amigos" with Salvadoran singer Álvaro Torres. The track peaked at number one on the U.S. Hot Latin Songs chart in 1991, the singer's first number one song. Subsequent singles, "Baila Esta Cumbia" and "Como la Flor", became popular songs on Mexican radio, with "Como la Flor" launching the singer's career in that country. "Como la Flor" peaked at number six on the Hot Latin Songs chart, despite popular culture claims that it was the singer's first number one single. The track has charted on the U.S. Regional Mexican Digital Songs list since its inception in 2010 and remains the singer's signature number and most popular recording. 
Selena singles discography
Selena's live recording entitled "Live" (1993) contained three studio tracks and produced two, top five U.S. singles "No Debes Jugar" and "La Llamada". After her collaboration with the Barrio Boyzz on the single "Donde Quiera Que Estés" peaked at number one on the Hot Latin Songs chart, Selena released her fourth studio album "Amor Prohibido" (1994). The album continued the singer's streak of US number one singles with "Amor Prohibido", "Bidi Bidi Bom Bom", "No Me Queda Más", and The Pretenders' cover "Fotos y Recuerdos". The latter peaked at number one posthumously following the shooting death of Selena on March 31, 1995. "Amor Prohibido" and "No Me Queda Más" became the most successful U.S. Latin singles of 1994 and 1995, respectively. At the time of her death, Selena was in the process of crossing over into the American pop market. Recording labels EMI Latin and EMI Records jointly released "Dreaming of You" several months after her death. Fearful that the song might cannibalize sales of the album in the U.S., EMI Records released "I Could Fall in Love" as a promotional single. It became the highest charting English-language song on the Hot Latin Songs chart for two years and became her first number one single in Canada. The title track, "Dreaming of You" became the highest charting "Billboard" Hot 100 song of the singer's career, peaking at number 22. Her cover of Pedro Infante's "Tú Sólo Tú" peaked at number one on the Hot Latin Songs for ten consecutive weeks; the longest number-one single of her career. "I'm Getting Used to You" peaked at number one on the U.S. Dance/Electronic Singles Sales; her first number one on that chart.
