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.

League of Legends

League of Legends (abbreviated LoL or just League) is a multiplayer online battle arena, real-time strategy video game developed and published by Riot Games for Microsoft Windows and Mac OS X. It is a free-to-play game supported by microtransactions and inspired by the mod Defense of the Ancients for Warcraft III: The Frozen Throne.

In League of Legends, players assume the role of an unseen "summoner" that controls a "champion" with unique abilities and battle against a team of other players or computer-controlled champions. The goal is usually to destroy the opposing team's "nexus", a structure which lies at the heart of a base protected by defensive structures. Each League of Legends match is discrete, with all champions starting off fairly weak but increasing in strength by accumulating items and experience over the course of the game.

League of Legends was generally well received at release, and grew in popularity in the years since. By July 2012, League of Legends was the most played PC game in North America and Europe in terms of the number of hours played. As of January 2014, over 67 million people played League of Legends per month, 27 million per day, and over 7.5 million concurrently during peak hours.

League of Legends Championship Series

The League of Legends Championship Series (LCS), formerly known as the Riot Championship Series, is the name of two professional League of Legends eSports leagues run by Riot Games. Twenty teams compete in two separate competitions in North America and Europe, with ten teams per continent. Each annual season of play is divided into two splits, spring and summer, both consisting of nine weeks of round-robin tournament play, which then conclude with play-off tournaments between the top six teams from each region. At the end of the season, the highest placing three teams in each league qualify for the annual League of Legends World Championship.

The LCS represents the highest level of League of Legends play in Europe and North America. The LCS has a promotion and relegation system; the bottom teams in the LCS from each split compete with the top teams from the Challenger Series (CS) to compete for spots in the next split of the LCS. The Challenger Series in each continent is composed of six teams: three teams which failed to advance in the previous promotion tournament, one team from the previous CS split, and the top two teams from ranked ladder play in the respective public League of Legends online game server.
