"Sunday Morning" is a song recorded by American rock band No Doubt.
 It was released as the sixth single from their third studio album "Tragic Kingdom" (1995).
 The single was made available as a CD single, cassette single, and VHS single on May 27, 1997 through Interscope.
 Lyrically, the song is about Gwen Stefani's relationship with Tony Kanal, and their breakup that followed.
 The track was written by band members Kanal, Gwen Stefani, and Eric Stefani, while production was handled by Matthew Wilder.
"The Invisible Man" is a song by the British rock band Queen, written by drummer Roger Taylor but credited to Queen.
 The song is sung mostly by Freddie Mercury, with vocal contributions from Taylor.
 Originally released on the album "The Miracle", it was released as a single in 1989.
 Taylor claims that he got the inspiration to create the song while reading a book (possibly the book of the same name), and the bassline instantly came to his imagination.
 This song marks the only time in any of Queen's songs that all four band members names are mentioned in the lyrics.
 The first being Freddie Mercury, followed by John Deacon.
 Brian May's name is then said twice (just before his guitar solo starts), and while saying "Roger Taylor", the first "r" is rolled to emulate the drums at the end of the verse.
 Freddie Mercury's name is said by drummer Roger Taylor, and the other ones by the lead singer Freddie Mercury.
This Is What the Truth Feels Like is the third studio album recorded by American singer and songwriter Gwen Stefani.
 It was released on March 18, 2016 by Interscope Records.

 However, after the underperformance of her 2014 singles and the writer's block Stefani suffered, she did not feel comfortable curating an album and scrapped the whole record in favor of starting again.
 The album's release was scheduled after Stefani hinted at it on her Twitter account.

Lover of Life, Singer of Songs (with the subtitle "The Very Best of Freddie Mercury Solo") is a compilation album of Freddie Mercury's solo songs.
 It was released (except in the U.S.) on 4 September 2006, the day before Mercury's 60th Birthday.
 It was released on 21 November 2006 in the U.S, three days before the 15th anniversary of Mercury's death.
"Too Much Love Will Kill You" is a song written by British guitarist Brian May of Queen, Frank Musker, and Elizabeth Lamers.
 The song reflected the breakdown of May's first marriage and attraction to his future wife, Anita Dobson.
 It was first recorded by Queen around 1988 or before, and was intended to be on the band's "The Miracle" album in 1989, but did not make the cut due to legal disputes following the band's decision that all songs on the album would be written by the group as opposed to individuals.
 After Freddie Mercury's death in 1991, May arranged a solo version, which he performed at the Freddie Mercury Tribute Concert in 1992, and subsequently included on his solo album "Back to the Light" that same year.
 Released as a single, it reached No. 5 on the UK Singles Chart.
 Because it was first played publicly at The Freddie Mercury Tribute Concert, a common misconception is that it was written as a tribute to Freddie Mercury, although it had actually been written several years before he died.

 He designed it based on her previous work with No Doubt, and Stefani later commented that it put her "on the yellow brick road to the No Doubt record I might do".
 "The Sweet Escape" is an apology for a fight between two lovers and describes a dream of a pleasant life for them.
 As the album's title track, its title was chosen to help market Stefani's music and fashion lines.
