"Eyes on Me" was Square's first attempt at a theme song with lyrics, yet it's plagued with silly grammatical mistakes that make it really akward so far for other singers to cover it, especially native English-speaking singers.
I have listened to Angela Aki and Susan Caraway attempt at fixing the mistakes when they covered it but it really sounded off. Whereas, some singers have covered it true to its lyrics and honestly, it just sounds silly.
I still can't believe Square actually released this song back then without any proofreading involved as they actually had Alex O. Smith to localize the game and could simply consult with him. I don't see this problem in later series either with "Melodies of Life," "1000 words," or "Answers" being fine with their lyrics.
