行く in songs pronounced "yuku", so what should the furigana be?

Hi everybody,

I have noticed that in songs the 行く is often pronounced ゆく.
According to the dictionary both is correct.
I assume that it's also easier to say, that's why one uses ゆく rather than いく.

But I'm wondering does the furigana must say い or ゆ?
I remeber sawing い once, but is it always い (since it's usually pronounced いく) or doesn't it matter?

I think there are certain situations where ゆく is more common than いく (such as on trains when denoting the next destination), but otherwise they are functionally identical. I'd say that if you're writing down the lyrics to a song that uses ゆく, then that should be what you write as the furigana as well.

Here's a really old thread on the topic:

OK, thanks, than I will try to write "yuku" in future (when it is sung like this).

You just rarely see that people write "yuku" in roomaji, probably 'cos they're just romanizing the whole text w/out listening or even after listening they don't bother to fix it (like I used to do).

Well OK, so that means for me: after I finish the romanization and listened to the music, fix also the "iku" if required.
