"Soldier's Joy" is a fiddle tune, classified as a reel or country dance.
 It is popular in the American fiddle canon, in which it is touted as "an American classic" but traces its origin to Scottish fiddling traditions, and Irish fiddle traditions.
 It has been played in Scotland for over 200 years, and Robert Burns used it for the first song of his cantata 'The Jolly Beggars'.
 According to documentation at the United States Library of Congress, it is "one of the oldest and most widely distributed tunes" and is rated in the top ten most-played Old Time Fiddle tune.
 According to the Illinois Humanities Center, the tune dates as early as the 1760s.
 In spite of its upbeat tempo and catchy melody, the term "soldier's joy" has a much darker meaning than is portrayed by the tune.
 This term eventually came to refer to the combination of whiskey, beer, and morphine used by Civil War soldiers.
"White Liar" is a song co-written and recorded by American country music artist Miranda Lambert.
 It was released in August 2009 as the second single from her album "Revolution".
 Lambert performed "White Liar" on "The Ellen DeGeneres Show" on October 6, 2009, and on the 2009 CMA Awards on November 11, 2009.
 In December 2009, the song became Lambert's second Top 10 hit and reached a peak of number 2 on the U.S. "Billboard" Hot Country Songs chart for the week of February 6, 2010.
 The song was written by Lambert and Natalie Hemby.
"Joy" is a pop/dance song performed by Australian actress/singer Toni Pearen.
 It was released in 1995 as the fourth and final single from her debut album "Intimate".
 "Joy" entered the ARIA top 100 singles chart on 19 March 1995 at #75, peaking at #71 the following week.
 "Joy" was released at a time when Pearen's music career was heading into decline.
 The album "Intimate" was unsuccessful and the previous single "Walkaway Lover" had charted lower than her first two singles, although it did make the top forty.
 "Joy" has so far been Toni Pearen's last single release.
The beginnings of Portuguese poetry go back to the early 12th century, around the time when the County of Portugal separated from the medieval Kingdom of Galicia in the northwest of the Iberian Peninsula.
 It was in this region that the ancestral language of both modern Portuguese and modern Galician, known today as Galician-Portuguese, was the common language of the people.
 Like the troubadour culture in the Iberian Peninsula and the rest of Europe, Galician-Portuguese poets sang the love for a woman, which often turned into personal insults, as she had hurt her lover's pride.
 However, this region produced a specific type of song, known as "cantigas de amigo" (songs of a friend).
 In these, the lyrical subject is always a woman (though the singer was male) talking about her friend (lover) from whom she has been separated - by war or other activities - as shown in the Reconquista.
 They discuss the loneliness that the woman feels.
 But some poems also project eroticism, or confess the lover's meeting in a secret place, often through a dialogue she has with her mother or with natural elements (such could be considered a custom adapted from the pagan peoples in the region).
 Epic poetry was also produced, as was common in Romantic medieval regions ("Gesta de D. Afonso Henriques", of unknown authorship).
"Liar" is a song by the British rock band Queen, written by the lead singer Freddie Mercury in 1970, and originally titled "Lover".
 The song featured on the band's 1973 debut album "Queen" and it makes prominent use of the flanging effect, especially on the drums and cowbell.
 A heavily truncated version of "Liar" was released as a single – backed with "Doing All Right" – in the United States by Elektra Records in February 1974.
 The music video consisted of the band miming to the song on a sound stage.
