"Despacito" (] ; English: "Slowly") is a single by Puerto Rican singer Luis Fonsi featuring Puerto Rican rapper Daddy Yankee from Fonsi's upcoming studio album.
 On January 12, 2017, Universal Music Latin released "Despacito" and its music video, which shows both artists performing the song in La Perla neighborhood of Old San Juan, Puerto Rico and the local bar La Factoría.
 The song's music video is the first video to reach over three billion views on YouTube.
 The song was written by Luis Fonsi, Erika Ender and Daddy Yankee, and was produced by Andrés Torres and Mauricio Rengifo.
The Carian language is an extinct language of the Luwian subgroup of the Anatolian branch of the Indo-European language family.
 The Carian language was spoken in Caria, a region of western Anatolia between the ancient regions of Lycia and Lydia, by the Carians, a name possibly first mentioned in Hittite sources.
 Prior to the late 20th century CE the language remained a total mystery even though many characters of the script appeared to be from the Greek alphabet.
 Using Greek phonetic values of letters investigators of the 19th and 20th centuries were unable to make headway and classified the language as non-Indo-European.
 Speculations multiplied, none very substantial.
 Progress finally came as a result of rejecting the presumption of Greek phonetic values.
Bimodal bilingualism refers to an individual or community's bilingual competency in at least one oral language and at least one sign language—"oral" and "sign" are the modes to which "bimodal" refers.
 A substantial number of bimodal bilinguals are Children of Deaf Adults or other hearing people who learn sign language for various reasons.
 Deaf people as a group have their own sign language and culture, but invariably live within a larger hearing culture with its own oral language.
 Thus, "most deaf people are bilingual to some extent in [an oral] language in some form".
 In discussions of multilingualism in the United States, bimodal bilingualism and bimodal bilinguals have often not been mentioned or even considered, in part because American Sign Language, the predominant sign language used in the U.S., only began to be acknowledged as a natural language in the 1960s (In discussions of bimodal bilingualism in the U.S., the two languages involved are generally ASL and English).
 However, bimodal bilinguals share many of the same traits as traditional bilinguals (those with competency in at least two "spoken" languages), as well as differing in some interesting ways, due to the unique characteristics of the Deaf community.
"A Brand New Day", also known as "Everybody Rejoice", is a song from the 1975 Broadway musical "The Wiz" written by American R&B singer and songwriter Luther Vandross.
 (In 1976 Vandross recorded a version of the song for his album "Luther", on Cotillion Records.)
 In the play, the song is sung to celebrate because Dorothy has killed Evilene, the tyrannical Wicked Witch of the West.
 Dorothy, the Tin Man, the Cowardly Lion, and the Scarecrow sing the song with the newly freed Winkies, who were ruled and enslaved by Evilene.
 It was later featured in the 1978 film version, sung by cast members Diana Ross, Michael Jackson, Nipsey Russell, and Ted Ross (credited as The Wiz Stars).
 Given the all-Black cast of "The Wiz", the song's many references to freedom and new possibilities (especially as sung by African American characters who had just been freed from enslavement) certainly invoked the struggles and history of Blacks in America.
 In the onscreen version of the song, Nipsey Russell can even be heard exclaiming "Free at last!"
—a reference to civil rights activist Martin Luther King Jr. (His impromptu addition to the song is not heard on the soundtrack album version, instead replaced by sung vocals by Diana Ross.)
"Ai no Uta" (愛のうた , Song of Love ) is an image song released in conjunction with the video game "Pikmin" for the Nintendo GameCube.
 The song was only used in commercials for the game and does not appear in the game itself, and those commercials appeared only in Japan.
 A small clip of the song though can be heard being sung by the Pikmin in "Pikmin 2", and the song is one of the default tracks available for the Distant Planet stage in "Super Smash Bros.
 Brawl" (along with a new, French language version).
 The song is sung by the virtual group Strawberry Flower, who also sang the theme song for "Pikmin 2".
 The title of the song translates to "Song of Love," so named because the song expounds on the emotions the Pikmin feel in relation to their involvement in the game.
Om Jai Jagdish Harey (Hindi: ॐ जय जगदीश हरे ) is a Hindu religious song for the deity Vishnu, however it also considered to be a monotheistic song.
 Although the religious hymn is a Hindi language composition, it is widely sung by many Hindus within the Indian Diaspora, regardless of their native language.
 The prayer is sung by the entire congregation at the time of Aarti, a form of Hindu worship.
Shuaib (] ), or Shuʿayb, or Shoaib (Arabic: شعيب‎ ‎ "šuʿayb"; meaning "who shows the right path"), was an ancient Midianite Prophet, sometimes identified with the Biblical Jethro (though Islam attributes to him many deeds not mentioned in the Bible).
 He is mentioned in the Quran a total of 11 times.
 He is believed to have lived after Abraham, and Muslims believe that he was sent as a prophet to a community: the Midianites also known as the People of the Tree since they used to worship a large tree.
 To the people, Shuʿayb proclaimed the faith of Islam and warned the people to end their fraudulent ways.
 When they did not repent, God destroyed the community.
 Shuʿayb is understood by Muslims to have been one of the few Arabian prophets mentioned by name in the Qur'an, the others being Saleh, Hud, and prophet Muhammad.
 It is said that he was known by early Muslims as "the eloquent preacher amongst the prophets", because he was, according to tradition, granted talent and eloquence in his language.
Caleno custure me (also spelled Calin o custure me) is the title of a song mentioned in Shakespeare's Henry V (IV,4).
 The context is on a Hundred years war battlefield, where an English soldier cannot understand his French captive and intending to answer in similar gibberish pronounces the title of the song.
Gnommish is the "fairy language" used in the "Artemis Fowl" series by Eoin Colfer.
 It is not actually a language at all, but the English language encoded into a letter-substitution cipher where each symbol represents a letter.
 Lines of translatable Gnommish run along the bottoms of books one, two, four, five and six.
 However, in book one of the series, it is mentioned that one of the symbols was comparable to the Egyptian Anubis symbol.
 It is also mentioned that Gnommish is a mix of symbolic and alphabetic letters, running in spirals (but since reading in spirals gives most fairies migraines, most modern fairy script is arranged in horizontal lines).
Luis Alfonso Rodríguez López-Cepero (born April 15, 1978), known by his stage name Luis Fonsi, is an American singer, songwriter and actor from Puerto Rico, best known for the worldwide hit song "Despacito".
