The Best of Sophie B. Hawkins is a compilation album released in 2002 collecting songs by American singer Sophie B. Hawkins.
 It is her first compilation album, and was released 10 years after her first studio album, "Tongues and Tails".
 It contains no songs from what was then her most recent album, "Timbre", released in 1999; instead, besides Hawkins' main singles (barring those from "Timbre"), it contains a variety of tracks from her first two albums that were not issued as singles, ending with an exclusive cover of "The Night They Drove Old Dixie Down", originally by The Band.
 The album was only released internationally, and not in Hawkins' home country of the United States.
 An album of the same title, also released as "Essential Sophie B. Hawkins", was issued the following year there.
Ultimate Hits: Rock and Roll Never Forgets is a compilation album by American rock singer–songwriter Bob Seger.
 The double-disc album was released on November 21, 2011 and contains 26 remastered tracks from throughout Seger's career, which spans more than four decades.
 Included are the original mono version of "Ramblin' Gamblin' Man", Seger's first hit with The Bob Seger System from 1968, the classic Christmas song "The Little Drummer Boy" from 1987's "A Very Special Christmas", which makes its first appearance on a Seger album, and previously unreleased cover versions of Tom Waits' "Downtown Train" and Little Richard's "Hey, Hey, Hey, Hey (Going Back to Birmingham)."
 There is also a Walmart exclusive edition that includes the bonus track "Living Inside My Heart," a song from the soundtrack of the 1986 film "About Last Night...", which has also never before been released on any Bob Seger album.
 Two songs on this compilation album are edited compared to the original releases: "We've Got Tonight" is the single edit, which is about one minute shorter than the album version, and "Katmandu" is a newly edited version which omits the second verse, making the song also about one minute shorter compared to the original album version.
 In the US it was certified gold and platinum in June 2013 by the RIAA.
"Papa Don't Preach" is a song by American singer Madonna from her third studio album "True Blue" (1986).
 The song was written by Brian Elliot with additional lyrics by Madonna, who produced it with Stephen Bray.
 The song also appears remixed on the 1990 compilation album "The Immaculate Collection" and in its original form on the 2009 compilation album "Celebration".
 The song's musical style combines pop and classical styling, and its lyrics deal with teenage pregnancy and abortion.
 It was based on teen gossip Elliot heard outside his studio, which has a large front window that doubles as a mirror where schoolgirls from the North Hollywood High School in Los Angeles regularly stopped to fix their hair and chat.
Michael McDonald (born February 12, 1952) is an American singer, songwriter, keyboardist and record producer.
One Night with You: The Best of Love, Volume 2 is the third compilation album released by American singer Luther Vandross, released on September 15, 1997 by Epic Records.
 It is his second compilation album to be released stateside, and is a continuation of his triple-platinum selling first compilation "The Best of Luther Vandross... The Best of Love" (1989).
 "One Night with You" contains four newly recorded songs including the R. Kelly-penned and Grammy-nominated "When You Call on Me/Baby That's When I Come Runnin'" and selections compiled from his later studio albums such as "Songs" (1994), "This Is Christmas" (1995), "Never Let Me Go" (1993), "Power of Love" (1991) and "Your Secret Love" (1996).
"Oh, Freedom" is a post-Civil War African-American freedom song.
 It is often associated with the American Civil Rights Movement, with Odetta, who recorded it as part of the "Spiritual Trilogy", on her "Odetta Sings Ballads and Blues" album, and with Joan Baez, who performed the song at the 1963 March on Washington.
 Baez has since performed the song live numerous times, both during her concerts and at other events.
 The song was first recorded in 1931 by the E. R. Nance Family with Clarence Dooley as "Sweet Freedom".
Over the years, the British hard rock band Uriah Heep has released 24 studio albums, 13 live albums, 16 compilation albums, 27 UK singles (33 worldwide) and 17 videos.
 The band's best selling album is "Sweet Freedom" which was released in 1972 and its worldwide sales are more than 4 million copies.
 Uriah Heep's progressive/art rock/heavy metal fusion's distinctive features have always featured massive keyboards sound, strong vocal harmonies and (in the early years) David Byron's operatic vocals.
 Twelve of the band's albums have made it to the UK Albums Chart ("Return to Fantasy" reached No. 7 in 1975) while of the fifteen "Billboard" 200 Uriah Heep albums "Demons and Wizards" was the most successful (#23, 1972).
 In the late 1970s the band had massive success in Germany, where the "Lady in Black" single was a big hit.
 With Black Sabbath, Deep Purple and Led Zeppelin, Uriah Heep became one of the top heavy metal and hard rock bands of the 1970s.
 It was there that the solid, but rather mainstream-sounding "Sweet Freedom" (No. 18 UK, No. 33 USA) was created with "Stealin'" released as a single.
 Having gained worldwide recognition, the band quit using fantasy lyrics and made an obvious stab at versatility by adding funk ("Dreamer") and acoustic folk ("Circus") elements to the palette.
Sweet Freedom (also known as Sweet Freedom – The Best of Michael McDonald in some countries) is a compilation album by American singer and songwriter Michael McDonald, released in 1986 on the Warner Bros. label.
 It reached #6 in the UK Albums Chart.
Episode II is the first mainstream studio album by Safri Duo, a percussion duo from Denmark that released six classical albums before its breakthrough with the Michael Parsberg-produced hit "Played-A-Live (The Bongo Song)", the opening track of the album.
 It was released on 26 June 2001 and reissued in 2002 with two additional tracks, including a cover version of "Sweet Freedom" with vocals by American R&B/soul singer Michael McDonald.
 Later the same year a Remix Edition of the album was released, which included an additional disc with remixes by artists such as Airscape, Cosmic Gate and Future Breeze.
"Home Sweet Home / Bittersweet Symphony", also known as "Bittersweet Home" is a song by American rock group Limp Bizkit.
 It was released in December 2005 as the only single from the compilation album "Greatest Hitz".
 The song is a medley of "Home Sweet Home" by Mötley Crüe and "Bitter Sweet Symphony" by The Verve.
 It is, along with the songs "Why" and "Lean On Me", the only new content on the "Greatest Hitz" compilation, and is the third cover song Limp Bizkit has released on an album (the others being The Who's "Behind Blue Eyes", and George Michael's "Faith").
