Miley Cyrus & Her Dead Petz is the fifth studio album by American singer Miley Cyrus, which was independently released for free online streaming on SoundCloud on August 30, 2015.
 Opting for an album relying less on computerized elements than her previous release, "Bangerz" (2013), Cyrus began planning the project in 2013 before "Bangerz" was released.
 Work continued into 2014 and 2015, when she befriended and began collaborating with the Flaming Lips.
 In addition to the psychedelic rock band, Cyrus worked with producers Mike Will Made It and Oren Yoel (with whom she had collaborated on "Bangerz").
 The album features guest vocals by Big Sean (who had appeared on "Bangerz"), Sarah Barthel of Phantogram and Ariel Pink.
The Wonder World Tour is the second concert tour by American recording artist Miley Cyrus.
 The tour was held to promote her second studio album "Breakout" (2008) and first extended play (EP) "The Time of Our Lives" (2009).
 It began in September 2009 and concluded in December 29, visiting cities in the United States and United Kingdom; thus, the Wonder World Tour became Cyrus' first world tour.
 It also became Cyrus' first tour not to incorporate performances as Hannah Montana, although "Let's Get Crazy", an official Hannah-song, was performed.
 Alternative band Metro Station served as opening act for all tour venues.
 It was sponsored by Wal-Mart and promoted by AEG Live.
 All tickets from the Wonder World Tour were sold using paperless ticketing, in order to prevent ticket scalping similar to what had occurred during Cyrus' previous tour.
 One dollar from each ticket sold was donated to the City of Hope National Medical Center, an organization devoted to the fight against cancer.
"BB Talk" is a song by American singer Miley Cyrus for her fifth studio album "Miley Cyrus & Her Dead Petz" (2015).

 "BB Talk" was supplemented with an accompanying music video on December 11, 2015, featuring Cyrus as an adult baby.
 Cyrus performed the track during her Milky Milky Milk Tour in November and December.

Younger Now is the sixth studio album by American singer Miley Cyrus.
 It was released on September 29, 2017, by RCA Records.
 It is her first full-length project since "Miley Cyrus & Her Dead Petz" (2015), and her first commercially released project since "Bangerz" (2013).
 Cyrus began planning a commercial follow-up record to "Bangerz" while simultaneously making "Miley Cyrus & Her Dead Petz" in 2015, although later became influenced by her reconciliation with fiancé Liam Hemsworth in 2016.
 "Younger Now" was written and produced by Cyrus and Oren Yoel, with whom she had collaborated on her previous two full-lengths.
 Not concerning herself with radio airplay, their efforts resulted in an "honest" final product that sees Cyrus "leaning into her roots."
 It features guest vocals from her godmother, country music singer Dolly Parton.
Hannah Montana 2: Meet Miley Cyrus is a double album by American singer and actress Miley Cyrus and her fictional character Hannah Montana from the television series of the same name.

 All twenty tracks are performed by Cyrus, although the first disc is credited to her character Hannah Montana in the vein of the original soundtrack, "Hannah Montana" (2006).
