How is subliminal/backmask messages placed in songs?
If a band wanted to backmask a track they would right out the message they wanted to convey and record it. Then they would listen to it backwards and then try to figure out words for the song that make sense when played forward. Then you have a backmasked song. However if you ever listen to a backmasked song such as Stairway to Heaven without subtitles it all sounds like absolute garbage. The only reason this came about was someone was looking for something bad to say and someone to point fingers at so they listened to the song over and over backwards trying to place words. Backmasking and subliminal messages are complete non-sense and works of science fiction. No proof exists that it works even after extensive scientific testing.
