Horror story here. I've got an older copy of Rosetta Stone with no dictionary, a Random House Dictionary, and vague familiarity with around 500 kanji (I practice about 300 per day), and I decided to take a crack at translating lyrics one day.
It was practically impossible. While Rosetta Stone uses non dictionary form words about 50% of the time, I'm able to get the jist of it between the pictures, my own lame dictionary, and some grammar guide called Japanese the Manga way (save your money, it's a 'little brown handbook' for Japanese).
But when I tried translating lyrics from the Visual Kei band
Gazette, I almost died. Even with some understanding of the differences of Dictionary and Spoken form, I was only able to locate/identify ONE in NINE words.
Please, for the love of all that is Japanese,
is there a dictionary that has the words these people actually speak?
