Songfacts®:

• This is the lead single from Miley Cyrus & Her Dead Petz, a homemade album created by the singer without financial support from her RCA Records label and released for free. Speaking to the New York Times, Cyrus said the record cost about $50,000 to make.
• The title of the album was inspired by the death of three pets: Cyrus' dog Floyd, her blowfish Pablow and a friend's cat Twinkle.
• The song was co-written by Cyrus with Wayne Coyne, who produced much of the album, and Coyne's Flaming Lips bandmates, Steven Drozd and Dennis Coyne. The four first worked together when Cyrus provided guest vocals on "With A Little Help From My Friends," which was part of the Flaming Lips' track-for-track tribute to the Sgt. Pepper album, With a Little Help from My Fwends.
• The raucous song finds Cyrus both singing about marijuana and begging for peace. "I think a lot of times we love to talk about things we wanna see and change but it's so easy to [just] talk about it," the singer told MTV News regarding the inspiration for the number. "It takes the energy and effort to actually go out and do it and make what you want actually happen."
• Having acted as host of the 2015 MTV Video Music Awards, Cyrus performed this with Wayne Coyne for the show's closing number.
