Wait I got something. This is something that I found on google. ~~
As with practically every other song on the planet,
aside from those where this concept was purposely
striven for, it's simply coincidental.
English has fifty-five phenomes, i.e. different
sounds which create the spoken language. And
when they're re-arranged, inverted, or altered
in some other similar fashion, then new words are
formed. The chances of those words resembling
actual English is to be expected, considering the
multitude of varied words in the language.
And no subconscious effort is put into leaving
reversed messages in normal speech. Paranoia
is the only thing definite about this situation.
