That's been my experience too. Seeing a bad job motivates me to do a better one, and also motivates me to confirm that my understanding is in fact correct. I think translations errors fall under two categories:
 * the translator thought they were right but they made a mistake; or
 * the translator had no idea what something means and guessed.

The first is hard to avoid. But I make it a point not to do the second unless I can indicate that the translation is tentative. Since we don't have a mechanism for that here, then if I'm not confident, I won't publish. It means I publish less, but at least I don't annoy people with shoddy work ...

What really annoys me thoug isn't seeing mistakes, but translators not having the same attitude. I told someone the other day that he was making simple grammatical mistakes, but he didn't seem to be that keen to do the hard work to fix that (though at least he was asking for help).

I know that translating songs is for enjoyment--it's not like translating government or business documents! So we shouldn't and mustn't set the bar too high. Plus, people need to practise to improve. But when a translation is so incorrect that it detracts from a listener's enjoyment, then such a translation is not fit for purpose.
