The Hot Dance Club Songs chart (also known as Club Play Singles, and formerly known as Hot Dance Club Play and Hot Dance/Disco) is a weekly national survey of the songs that are most popular in U.S. dance clubs. It is compiled by Billboard exclusively from playlists submitted by nightclub disc jockeys who must apply and meet certain criteria to become "Billboard-reporting DJs."

The current number-one song on the Hot Dance Club Songs chart for the issue dated June 9, 2012 is "Where Have You Been" by Rihanna.

Hot Dance Club Songs has undergone several incarnations since its inception in 1974. Originally a top-ten list of tracks that garnered the largest audience response in New York City discothèques, the chart began on October 26, 1974 under the title Disco Action. The chart went on to feature playlists from various cities around the country from week to week. Billboard continued to run regional and city-specific charts throughout 1975 and 1976 until the issue dated August 28, 1976, when a thirty-position National Disco Action Top 30 premiered. This quickly expanded to forty positions, then in 1979 the chart expanded to sixty positions, then eighty, and finally reached 100 positions from 1979 until 1981, when it was reduced to eighty again.

Nancy Maureen Argenta (born Nancy Maureen Herbison on January 17, 1957) is a Canadian soprano singer, best known for performing music from the pre-classical era. She has won international acclaim, and is considered by many as the leading Handel soprano of her time.

She was born in Nelson, British Columbia, Canada. She spent her early years in the settlement of Argenta, from which she later took her professional name (to avoid being mistaken for another Canadian soprano, Nancy Hermiston.)

At the age of 11 she started formal voice lessons with Dr. Amy Ferguson of Nelson, and sang with one of the school choirs at L.V. Rogers High School in Nelson. By that time, she was frequently making trips to Vancouver, British Columbia, so she could hear musical events and have additional singing lessons. After graduation from high school in 1975, she was a student of Jacob Hamm in Vancouver and of Martin Chambers at the University of Western Ontario, graduating in 1980. The same year she won 1st prize in the Sophie Carmen Eckhardt-Gramatté Competition. After further training with Jacqueline Richard in Düsseldorf from 1980 to 1981, and with Gérard Souzay, in 1982 she settled in London, England and completed her studies with Vera Rozsa and Sir Peter Pears. In 1990, she won Canada's Virginia Parker Prize.

Henry Purcell ( /ˈpɜrsəl/; 10 September 1659 (?)– 21 November 1695), was an English composer. Although incorporating Italian and French stylistic elements into his compositions, Purcell's legacy was a uniquely English form of Baroque music. He is generally considered to be one of the greatest English composers; no other native-born English composer approached his fame until Edward Elgar.

Purcell was born in St Ann's Lane Old Pye Street, Westminster. Henry Purcell Senior, whose older brother Thomas Purcell (d. 1682) was also a musician, was a gentleman of the Chapel Royal and sang at the coronation of King Charles II of England. Henry the elder had three sons: Edward, Henry and Daniel. Daniel Purcell (d. 1717), the youngest of the brothers, was also a prolific composer who wrote the music for much of the final act of The Indian Queen after Henry Purcell's death. Henry Purcell's family lived just a few hundred yards west of Westminster Abbey from the year 1659 and onward.

After his father's death in 1664, Purcell was placed under the guardianship of his uncle who showed him great affection and kindness. Thomas was himself a gentleman of His Majesty's chapel, and arranged for Henry to be admitted as a chorister. Henry studied first under Captain Henry Cooke (d. 1672),Master of the Children, and afterwards under Pelham Humfrey (d. 1674), Cooke's successor. Henry was a chorister in the Chapel Royal until his voice broke in 1673, when he became assistant to the organ-builder John Hingston, who held the post of keeper of wind instruments to the King.
