It's actually messaging when the song is actually played backwards. Such as the word "Love" being said as "Evol", and just coincidentially sounding like the word "Evil". It's just one of the words that may have an opposite meaning, but I doubt it was placed there to embed satanic messages into peoples' subconcious.I can understand getting caught up in this sort of thing because of your religion, but I don't believe something as innocent as Barney's theme song can have a large impact on children because of something played backwards.
