Services and productsEdit

The content was initially published in book form in 1991 as the All Music Guide, and is now freely available to the public for online reference and information as well as available via licensing for point-of-sale systems, media players, and online music stores.[6][15][16]

It offers limited information about Television productions, focused mainly on those released on DVD. Like AllMusic, this content is also available via licensing to point-of-sale systems, media players, and online stores.[6][17][18]

Content and data managementEdit

RhythmOne's database was initially set up by Vladimir Bogdanov to hold the information of Erlewine's many lists.[6]

Information in the database is licensed and used in point-of-sale systems by some music retailers, includes the following:

  • 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.

The company 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.[citation needed]

Business modelEdit

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.[6]

All Media Network licenses large databases of metadata about movies, video games, audio books, and music releases from Rovi Corporation and publishes them online for consumer use. This includes credits, and staff-written biographies, reviews, ratings, and recommendations as well as categories such as theme or mood.[11] Rovi also makes this content available for point of sale systems in stores globally, for CD and DVD recognition in software media players such as Windows Media Player and Musicmatch Jukebox, and for providing content for a variety of websites including iTunes, Pandora, and Spotify.[22][23]

Formerly, All Media Guide sold print compilations of its information.[7]
