Or rather, why is it different?
I bought this CD of my fave Band's Japanese album. The lyric booklet is in Japanese (and partly English since the song has English parts). I can read a little Japanese. And I noticed that there were some parts which could be spelled in Kanji yet it's in Hiragana. And on some parts some of the English words are Japanized when some aren't (i.e. message and メセージ).
So, how or why is it different? Or is it just the same no matter how they are spelled?
