The WT was a pale imitation of all the Religious Right's hulabaloo against "rock music" in the 80s. They even went into claims of "backward masking," trying to convince that if you played Queen's lyric "Another one bites the dust" (slurred as "Annudawom baatz da duzt.") you would hear "Start to smoke marijuana." It's more than likely that sound-engineers in the music industry implant their little jokes, but consider this...
from SATANISM IN AMERICA: How the Devil Got Much More Than His Due by Carlson and O'Sullivan. They mentioned that the human mind is great at pattern-recognition, even when the patterns aren't actually there. If you listen to Beethoven's Ninth Symphony but you don't speak German, you will tend to interpret the choral singing into English words. Thus you will hear phrases encouraging alcoholism such as "I'm not sober; been drinking Miller." You will also hear "Heineken," a brand of beer. You will also hear a rousing chorus celebrating steam-power: "Boiler engine, boiler engine, boiler engine, boiLERR, enGEEEN..." [although what that could mean to encourage young teens to perdition is left up to the Faithful Slave to figure out.]
