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.

Braxton topped the Billboard 200 with her 1993 self-titled debut album and continued that streak with her second studio album Secrets, which spawned the number-one hits "You're Makin' Me High" and "Un-Break My Heart". Although she had successful albums and singles, Braxton shortly filed for bankruptcy, but then returned with her chart-topping third album, The Heat. In 2009, she returned to the spotlight with "Yesterday", a #12 R&B hit which serves as the first single off her new album Pulse, released on May 4, 2010, which debuted at #1 on Billboard R&B Album Chart. Braxton was involved in the 7th season of the reality show Dancing with the Stars. Her professional partner was Alec Mazo. She was voted off in week five of the competition. It was announced on October 6, 2010 that Braxton once again had filed for bankruptcy. A reality series entitled Braxton Family Values, starring Toni and her sisters, debuted April 12, 2011 on WE tv. WE tv ordered a 13-episode second season of the show after the third episode of the first season. On September 18, 2011, Braxton was inducted into the Georgia Music Hall of Fame.

Nicole Atkins (born October 1, 1978) is an American singer-songwriter. She has been compared to Roy Orbison and singers from the Brill Building era.

Atkins was born in Neptune, New Jersey. She grew up in Shark River Hills, a middle class enclave within Neptune overlooking the Shark River. Atkins has cited the river (technically a bay) as a major inspiration for her music, particularly the imagery of “the river in the rain” found in the title track on her album Neptune City. She started playing piano when she was 9 and taught herself to play guitar at 13. She eschewed more popular acts of the day for musical groups her parents listened to, such as The Ronettes and Johnny Cash. She has cited The Sundays’ Harriet Wheeler as a major early influence.

She started playing in pick-up bands and doing gigs at local coffeehouses while attending St. Rose High School in the nearby town of Belmar.

Against Me! is an American punk rock band formed in Naples, Florida in 1997 by singer and guitarist Tom Gabel. Since 2002 the band's lineup has also included guitarist James Bowman and bassist Andrew Seward; current drummer Jay Weinberg joined in 2010. After releasing three studio albums through independent record labels, Against Me! moved to Sire Records for 2007's New Wave, which reached no. 57 on the Billboard 200. Their fifth and most recent album, 2010's White Crosses, was their most successful, reaching no. 34. In 2011 the band launched their own record label, Total Treble Music, through which they plan to release future albums. In 2012 Gabel publicly came out as transgender, with plans to begin a medical process to live as a woman and eventually take the name Laura Jane Grace while continuing to front Against Me!. The first album expected to feature Laura Jane Grace as frontwoman is Transgender Dysphoria Blues.

Against Me! was formed in 1997 by singer/guitarist Tom Gabel as a solo act, occasionally performing with backing musicians. The first Against Me! release was an eponymously-titled 1997 cassette demo. With the addition of drummer Kevin Mahon, a second demo, Vivida Vis! (1998), was released in limited numbers by Misanthrope Records. The band's first EP, Against Me!, was released in 2000 through Crasshole Records. Their first widely-distributed release was the EP Crime as Forgiven by Against Me! (2001), released by Plan-It-X Records and Gabel's own Sabot Productions. A third EP, an eponymously-titled acoustic recording by Gabel and bassist Dustin Fridkin, was released later that year.
