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.

User-generated content

User-generated content (UGC) is defined as "any form of content such as blogs, wikis, discussion forums, posts, chats, tweets, podcasts, digital images, video, audio files, advertisements and other forms of media that was created by users of an online system or service, often made available via social media websites". It entered mainstream usage during 2005, having arisen in web publishing and new media content production circles. It is used for a wide range of applications, including problem processing, news, gossip and research and reflects the expansion of media production through new technologies that are accessible and affordable to the general public. Additionally, user-generated content may also employ a combination of open source, free software, and flexible licensing or related agreements to further reduce the barriers to collaboration, skill-building and discovery ("'UGC'") has also gained in popularity over the last decade, as userbases have grown on social media and content-based sharing sites.

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."
