That's right, these lyrics are backwards. That is intended; which song is sung in Japanese, except for a single English line, as well as this backwards lyric in English scattered throughout?
From Quiz Utada
Answer:
Passion
"Passion" was originally released in 2005 on Utada's "Ultra Blue" album. The song was used as the theme for "Kingdom Hearts II". An English version of the song, "Sanctuary", was used for the game internationally, but was not released on an album until her 2009 US release of "This Is the One".
"Passion" is mainly Japanese, save for the line "my heart's a battleground." "Sanctuary" is the English version. Both contain some of the exact same lyrics, however. If you are familiar with the song, perhaps you've heard some mumbo jumbo throughout; that is actually her singing "I need more affection than you know", but played backwards. Listen carefully, you can hear the words in your mind backwards.
