Alterna lyrics- is it "Hey, come on" or "Henka wo"?

[Delirium-Zer0]

I think it makes more sense as what masa's given us. I don't have the single yet, haven't seen the lyrics, but based on what it means, it makes more sense in context.

I don't care if you sing it differently in your own personal arena, singing along at home, whatever. That's up to you.

But if anyone sings it as "hey come on" at anime expo karaoke or anything like that I AM gonna get a bit irked because i'm weird like that. (Then again, i'm the type never to learn song lyrics until all the official lyrics are out there, just to be sure. I'm a big one for authenticity.)
