=== Backmasking ===
{{Main|Backmasking}}
Backmasking is a [[sound recording and reproduction|recording]] technique in which a message is recorded backwards onto a track that is meant to be played forwards. It was popularized by [[The Beatles]], who used backward vocals and instrumentation on their 1966 album ''[[Revolver (Beatles album)|Revolver]].'' The technique has also been used to censor words or phrases for "clean" releases of songs{{Citation needed|date=April 2008}}.

Backmasking has been a controversial topic in the United States since the 1980s, when allegations of its use for Satanic purposes were made against prominent [[rock music]]ians, leading to [[Book burning|record-burnings]] and proposed anti-backmasking legislation by state and federal governments. In debate are both the existence of backmasked Satanic messages and their purported ability to subliminally affect listeners.{{Citation needed|date=October 2016}}
