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 Ann Arbor, Michigan, United States.

AllMusic's database, which is licensed and used in point-of-sale systems by some music retailers, includes:

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.

Iggy Pop (born James Newell "Jim" Osterberg, Jr.; April 21, 1947) is an American singer, songwriter, musician, and actor. Though considered an innovator of punk rock, Pop's music has encompassed a number of styles over the years, including pop, metal, jazz and blues. Pop became known as 'Iggy' in high school, during which time he served as drummer for local blues band The Iguanas. He is vocalist of influential protopunk band The Stooges (Pop and the other surviving members of the group reunited in 2003), having become known, since the late 1960s, for his outrageous and unpredictable stage antics.

Though the singer's popularity has waned and waxed throughout his career, Pop has recorded a number of well-known songs, including "Lust for Life", "Real Wild Child", "I Wanna Be Your Dog," "Candy" (a duet with Kate Pierson of The B-52's), "China Girl", "Nightclubbing", "Search and Destroy", and "The Passenger". The Stooges were inducted into the Rock and Roll Hall of Fame in 2010

Iggy Pop (AKA Iggy Stooge) was born in Ann Arbor, Michigan, the son of Louella (née Christensen) and James Newell Osterberg, Sr., a former high school English teacher and baseball coach at Fordson High School in Dearborn, Michigan. Osterberg was raised in a trailer park in Ypsilanti, Michigan. He is of Irish and English descent on his father's side, and of Norwegian and Danish ancestry on his mother's. His father was adopted by a Swedish American family and took on their surname (Österberg).
