I know. But then in a lot of songs there are phrases that are sung but they aren't written down, so we have to follow the official lyrics and not include those extra singing parts. Just don't include those, they're not written in the lyrics and weren't intended to probably. =/

Just because it's the written piece, it doesn't mean it's correct. It's not perfect. It's good to follow the original, but it may be not correct.
I can clearly hear "hold", the "you" is debatable. It could be ooh ooh, or "you" which makes more sense in my opinion. I won't make a big deal out of this though, it's just one line. Even then, I would prefer if there weren't wrong details on the lyrics.

Yes, all other parts of the lyrics are correct.
Just do not add the "hold, you... you..." part at the end. It is NOT in the lyrics.
Just because you can hear certain phrases does not mean it's included in the written lyrics.
Maybe even locking these lyrics would be a good idea.

Are other parts of the lyrics all correct?

I know. But they shouldn't be written down if they aren't included in the cd's lyrics.

But... I can clearly hear "I just wanna hold, you... you..." in the song...

The "kono mama
I just wanna hold hold
ooh, ooh"

Should just be
"Kono mama
I just wanna"

Because those parts are not included in the lyrics.
