Have you ever listened to Stairway to Heaven?
"If there's a bustle in your hedro do not be alarmed now"
… now what does this mean?
Subliminal messages in music are in many songs and in Stairway to Heaven should you play the previously mentioned line backwards, it is claimed you will hear someone say "I've been a bad boy, 666 satan". These messages in music are often put there for strictly entertainment purposes.
Rumor has it that Led Zeppelin – the band that wrote and performed Stairway to Heaven – put these subliminal messages in the music they wrote because at the time, when someone played their record backwards enough, they had a strong likelihood of destroying their record and thatus having to purchase another one would result in more sales.
More sales resolved in Led Zeppelin holding the number 2 spot in record sales. Subliminal messages in music were mastered by the Beatles. The Beatles have many subliminals in the music they wrote and most famously in "Come Together". Come together is cleverly named, and is said to talk about sex with John Lennon.
Other notable artists withable subliminal messages in music that were written include Britney Spears. Britney Spears, at a young age stated that she was a virgin and would stay that way until she got married. However in her song "I'm not that innocent" there is a section which when played back produces "Sleep with me I'm not too young".
Subliminal messages in music can be used to allow someone to look a certain way to those that know the music and tell their real message to their fans. Take for instance Queen's "Another One Bites the Dust". When played normally, it tells the story of warriors getting killed in battle, but when played back it talks about how fun it is to use drugs.
Subliminal messages in music will increase as long as rules and regulations are in place on what musicians can write about. After all, they would not be good at their job if they did not rebel!
