Ayumi Hamasaki (浜崎 あゆみ , Hamasaki Ayumi , born October 2, 1978) is a Japanese recording artist, lyricist, model, and actress.
 Through her entire career, she has written all her lyrical content, produced her own music, and has sometimes co-composed her music.
Let Me Feel Your Power is the tenth live album by British heavy metal band Saxon.
 The title comes from the third track on their seventeenth studio album, The Inner Sanctum.
 Originally, it was to be released on 23 September 2016, but the release date was pushed back to 7 October 2016.

"Be with Me" is the debut single co-written and performed by R&B singer–songwriter J. Holiday released off of his debut album "Back of My Lac'".
 It was to be released early 2007, following the single.
 However, due to the single failing to top the charts peaking at #83 on the Hot R&B/Hip-Hop Songs and completely missing the "Billboard" Hot 100 all together, the album was pushed back to an unspecified fall release date, until finally being released October 2, 2007, following the success of his second single titled "Bed".
 The single's promotion fell through due to the merging of Capitol & Virgin Records, LeToya Luckett, Mims, Cherish, and Chingy had cancelled third singles, and Chingy was let go from the label, while J. Holiday's promotion for the song was also canceled.

Universal Mind Control is Common's eighth studio album.
 Originally scheduled to be released on June 24, 2008 under the name "Invincible Summer", the release date was pushed back to September 30, 2008 due to Common filming "Wanted".

 Later, the release was pushed back to December 9, 2008.
Live the Life is an album by Michael W. Smith.
 One notable song on this album was "In My Arms Again," which Michael W. Smith wrote for the film "Titanic".
 There were 26 songs written and completed for the album, whose release date was pushed back twice as Smith wasn't fully satisfied with the track list.
 Along with the 12 songs which eventually made it on the album, the tracks "Greater Than We Understand" and "Evening Show" were released on the B-sides of the CD singles for "Live the Life" and "Love Me Good" respectively.
 The remaining 12 songs appeared in some form on Smith's 1999 album This Is Your Time.
