Errors in Korean lyrics

I know I wrote less than 36 hours ago that I'm not going to write in this blog again. But I am irritated by this issue, and I have nowhere else to write this.
Why are there so many errors in the Korean lyrics? I guess they are made by non-Korean speakers, since most of them are typos. For instance, the lyrics said 펴고, but it was written as '긔고'. They kinda look similar if it's written in a small font, so I can guess why these kind of typos were made.
Still, that doesn't excuse these errors. The romaja is transliterated according to these Korean lyrics, so if the Korean lyrics are wrong, the romaja is wrong. It's not a huge job or anything, but it's really bothersome when you have to fix both of them.
At least if it's an obvious typo like the one above, it's okay. But sometimes the typos form actual words, and those kind of typos make me mistranslate. And that is irritating.
Well, since Korean is my first language and I don't transliterate, I guess I can't just criticize these errors. So all of the above was just me, ranting about. I'll just have to hope that the 13 remaining songs have perfect Korean lyrics. Off to check.
