I heard them all.
I am a radio DJ and got on earful about some of those songs.
It is called back masking and it's where they attempt is made to conceal a message in a song but you can only hear it backwards. You would have to literally get your vinyl record and move it backwards to hear LOL.
It was hard to do with most peoples turntables at the time but having access to the proper equipment I was able to do it. I found it to be bunk.
Hotel California had all kinds of occult connections although I don't recall it having back masking.
Another One Bites The Dust supposedly has the back masked message "decide to smoke marijuana".
Stairway to heaven said things like "praise Satan" and other nonsense.
The back masking thing was really a big story in the 80s and early 90s and Tipper Gore even lobbied congress to have albums labeled warning of the content.
Judas Priest even went to court over it.
From Wikipedia...
In the middle of 1990, the band was involved in a civil action that alleged they were responsible for the self-inflicted gunshot wounds in 1985 of 20-year-old James Vance and 18-year-old Raymond Belknap in Sparks, Nevada, USA.[24] On 23 December 1985, Vance and Belknap, after hours of drinking beer, smoking marijuana and allegedly listening to Judas Priest, went to a playground at a church in Sparks with a 12-gauge shotgun to end their lives. Belknap was the first to place the shotgun under his chin. He died instantly after pulling the trigger. Vance then shot himself but survived, suffering severe facial injuries. Following numerous complications, Vance too died in 1988, three years after the suicide pact.[25]
The men's parents and their legal team alleged that a subliminal message of "do it" had been included in the Judas Priest song "Better By You, Better Than Me" (a cover of the Spooky Tooth number) from Stained Class (1978). They alleged the command in the song triggered the suicide attempt.[24] The trial lasted from 16 July to 24 August 1990, when the suit was dismissed after the judge ruled that the so-called "do it" message was a result of an accidental mixup of background lyrics.[24] One of the defence witnesses, Dr. Timothy E. Moore, wrote an article for Skeptical Inquirer chronicling the trial.[24] The trial was covered in the 1991 documentary Dream Deceivers: The Story Behind James Vance Vs. Judas Priest.
It's a completely different atmosphere today in congregations. An elder here even has his own rock band! LOL
Funny story, this elders band was playing a witness gig and they busted out "La Grange", the ZZ Top number.
For those that don't know, it's is a song about a brothel. Anyway, I started cracking up about it and mentioned it to some others at our table. Word got back to this elder and he apologized one night at the meeting and said they wouldn't be doing it again. I laughed and said no biggie to me. At least you weren't doing "pearl necklace".
He didn't know what that was and I said look it up. and then said no wait don't do that. take my word for it. I bet he looked it up :-)
