My question is about a line from a the song "Innocent Arrogance". The relevant
verse goes like this:

> 見せたくないものばかりを  
>  見せないから  
>  大事なものさえも見つからない  
>  綺麗なままでいることは **できないじゃない**  
>  僕らは 僕らは 進もう

I've marked in bold what I perceive as double negation. However, multiple
translation and Google Translate indicate that there is no double negation
here. The translations I was able to find say that it means "You can't stay
pretty\clean forever" but I don't see how that is possible when できない is
immediately followed by じゃない.

Thanks!

Why できないじゃない isn't double negation?
