Electro house

Electro house is a form of house music. Electro house is characterized by a prominent bassline and/or kick drum and a tempo between 125 and 135 beats per minute. Its origins were influenced by electro,electroclash,electropop,synthpop, and tech house. The term has been used to describe the music of many DJ Mag Top 100 DJs, including Dimitri Vegas & Like Mike, Hardwell, Skrillex, and Steve Aoki.

Characteristics

Electro-house is typified by its heavy bass. This is often in the form of buzzing basslines, such as those created with sawtooth waves and distortion. It is also often in the form of large bass drum sounds in a four-to-the-floor pattern. The tempo of electro house is usually around 130 beats per minute. Electro house sometimes resembles tech house, but it can contain melodic elements and electro-influenced samples and synths.

History

The genre has been described as a fusion genre of house and electro, either in its original form or as fused with electropop and techno in its late-1990s revival, electroclash. The word electro is now often used as an adjective, such as electro-house and electro-pop.

Facebook

Facebook is a corporation and online social networking service headquartered in Menlo Park, California, in the United States. Its website was launched on February 4, 2004, by Mark Zuckerberg with his Harvard College roommates and fellow students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes. The founders had initially limited the website's membership to Harvard students, but later expanded it to colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support for students at various other universities and later to high-school students. Since 2006, anyone who is at least 13 years old was allowed to become a registered user of the website, though the age requirement may be higher depending on applicable local laws. Its name comes from the face book directories often given to American university students.

After registering to use the site, users can create a user profile, add other users as "friends", exchange messages, post status updates and photos, share videos, use various apps and receive notifications when others update their profiles. Additionally, users may join common-interest user groups, organized by workplace, school or college, or other characteristics, and categorize their friends into lists such as "People From Work" or "Close Friends". Also users can complain or block unpleasant people. Facebook had over 1.18 billion monthly active users as of August 2015. Because of the large volume of data users submit to the service, Facebook has come under scrutiny for their privacy policies. Facebook, Inc. held its initial public offering in February 2012 and began selling stock to the public three months later, reaching an original peak market capitalization of $104 billion. On July 13, 2015, Facebook became the fastest company in the Standard & Poor's 500 Index to reach a market cap of $250 billion. Following its Q3 earnings call in 2015, Facebook's market cap soared past $300 billion.

Music

Music is an art form and cultural activity whose medium is sound and silence. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and with vocal techniques ranging from singing to rapping, and there are solely instrumental pieces, solely vocal pieces and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."

Greatest hits album

A greatest hits album, sometimes called a "best of" album or a catalog album, is a compilation of songs by a particular artist or band. Most often the track list contains previously released recordings with a high degree of notability. However, to increase the appeal, especially to people who already own the original release, it is common to include remixes and/or alternate takes of popular songs; even new material (previously unreleased). At times a greatest hits compilation is the original release for songs that have themselves been released as a single and charted successfully.

Notable compilations

Madonna's The Immaculate Collection is the best selling greatest hits compilation by a solo artist; all of the songs on it are presented in different versions than the original hit versions. The Eagles' Their Greatest Hits (1971–1975) is the best selling greatest hits compilation by a group and also one of the ten best selling albums in history. Greatest hits albums are typically produced after an artist has had enough successful songs to fill out an album release. Some artists, such as Mariah Carey, Madonna, Janet Jackson, Britney Spears, Elvis Presley, Michael Jackson, The Beatles, Kenny Rogers, Aerosmith, Kiss, U2, Dolly Parton, Journey, Los Tigres del Norte, Queen, Kylie Minogue and Billy Joel, have released multiple greatest hits albums through their long careers. Some greatest hits albums are released only at the end of the artist or group's career. For example, My Chemical Romance released a greatest hits album after they disbanded. Other artists, like Eminem have released hits albums in the center of their success. He released Curtain Call: The Hits in 2005 and then Shady XV as a compilation album in 2014.
