Allmusic (previously All Music Guide or AMG; stylized as allmusic) is an online music guide service, owned by All Media Guide.
Allmusic was founded in 1991 by popular-culture archivist Michael Erlewine as a guide for consumers.
Its first reference book was published the following year. When first released onto the Internet, AMG predated the World Wide Web and was first available as a Gopher site.
AMG headquarters is located in Statesville, North Carolina, United States.
Allmusic's database, which is licensed and used in point-of-sale systems by some music retailers, includes:
Basic data: names, genres, credits, copyright information, product numbers.
Descriptive content: styles, tones, moods, themes, nationalities.
Relational content: similar artists and albums, influences.
Editorial content: biographies, reviews, rankings.
Allmusic also claims to have the largest digital archive of music, including about six million digital songs, as well as the largest cover art library, with more than half a million cover image scans.
The Allmusic database is also used by several generations of Windows Media Player and Musicmatch Jukebox to identify and organize music collections. Windows Media Player 11 and the integrated MTV Urge music store have expanded the use of Allmusic data to include related artists, biographies, reviews, playlists and other data.
