Ok well if those backwards lyrics really ARE there [not talking about i need more affection than you know, i need true emotions, or so many ups and downs], then they would be there as a form of backmasking, which a lot of artists actually use. If a song is backmasked with secret lyrics, then what the song sounds like forwards will be completely different played backwards. Er, what I mean is, if someone sings "The sky is blue" but uses backmasking, then that "The sky is blue" line could sound like "I have a red car" backwards, and it'll be clear, not warped. So if Sanctuary was really backmasked [which it would have had to be for lyrics THAT specific], then if you record someone singing Sanctuary and reverse that [without doing anything else to meddle with the song], then that sound byte would sound completely different.
So I did this, and the sound byte of me singing Sanctuary backwards sounds exactly the same [word wise] as when you play the original version by Hikki backwards.
Therefore it's all in our heads.
Um did I make any sense? it's late and I tend to ramble at this hour...
