Context: On a Storyteller's Night is the fifth studio album by the English rock band Magnum, released in 1985 on FM Records in the UK and on Polydor Records in Germany.  The album is widely considered as Magnum's breakthrough album.  This album features one of Tony Clarkin's most thoughtful songs, "Les Morts Dansants" — a simple song in that paints a picture of a man being executed by a firing squad.  It is the way in which the song accomplishes this, with some very colorful and imaginative metaphors.  The song was covered in 1987 by the American singer Patty Smyth of the band Scandal on her first solo album "Never Enough", but because of its French title the song was retitled "Call To Heaven". "Love" is a song by American singer Lana Del Rey.  It was released on February 18, 2017, through Polydor Records and Interscope Records, as the lead single from her fifth studio album, "Lust for Life" (2017).  The song was written and produced by Del Rey, Benny Blanco, Emile Haynie and Rick Nowels, with additional production by Kieron Menzies.  Its release was first teased with promotional posters hung in Los Angeles on February 17, after which the release date was pushed up due to leaked versions of the song surfacing online the same day.

The album was produced mostly by Dr. Dre and Eminem, along with The 45 King, the Bass Brothers, and Mel-Man.

The album marked a departure from the more guitar-driven instrumentation of Del Rey's previous album "Ultraviolence" and a return to the baroque pop of "Born to Die" and "Paradise".

Born to Die: The Paradise Edition is the reissue of American singer and songwriter Lana Del Rey's second studio album "Born to Die" (2012).
