Gekokujou

Gekokujou

In a couple of places the romaji doesn't match the japanese lyrics:

Niko de no ore no atsukai wa shota (ニコでの俺の扱いはショタ )

Ikka-soude de tanka o kitta (一家総出で啖呵切った)

I also have a question about

chotto imeeji chigau n de nai (ちょっとイメージ違うんでない)

I can usually manage appended negations in English or Greek but they confuse me no end in Japanese. Does it mean

Your image of me is somehow wrong, don't you think?

as translated, or

[That] image [of me] is not the slightest wrong.

Both interpretations can fit the context, either referring to the incorrect shota image or to the correct otoko image. A Japanese native speaker once told me that in songs, an appended negation like this really means negation, i.e., it would mean chigawanai. However, this is not your typical song.

Fixed the romaji!

As for your question, I'm not really sure about んでない because that's a weird construction I haven't encountered before and can't turn up anything about by googling, but if it were んじゃない I would say the current translation is correct? But then I've never heard about songs using んじゃない differently from other writing/speech, so if a native speaker told you that then maybe I'm wrong.

I got around to asking Damesukekun (a native Japanese speaker) and he said that the interpretation as translated is correct.

FYI ja nai is a contraction of de wa nai. I'm not sure what the subtleties are of omitting the wa, but I believe de nai means pretty much the same thing.

I'm sorry, I didn't think it was necessary to clarify that I know that じゃない is a contraction of ではない, which is one of the first things I learned as a beginner in Japanese thirteen years ago. I had not seen, specifically, "んでない" without "は".

Oops sorry if I phrased it badly ... I wasn't implying you didn't know that, just setting the context for the next statement.

I'm sorry, I shouldn't have been so snippy.
