How, you may ask? Here are just the simplest ways that I could think of off the top of my head:

Translate articles on Wikipedia (or any smaller wiki)

Translate song lyrics on Musixmatch

Use platforms like Crowdin, Weblate or Translatewiki to help translate open source software

maybe i'm the one hearing them wrong, but some of them mistakes make no sense for the song anyways?? like whoever jumped on to musixmatch and tippety tapped away must have been rushing or copying from someone who was because how do you mess up nothing at all so bad, and in such a way that every other lyric website chooses to copy you?? (and i don't mean this to attack anyone i'm just annoying and bothersome)

like this just makes no sense period. as a normal sentence, this would be clunky and not really flow right. "happiness is itself desire, so long as the fire getting weak, contained" just... sounds wrong. but it's on at least two websites. me, i'm pretty sure it's supposed to be "happiness is itself desire, so long as the fire can be contained" because doesn't that make more sense???

it makes you go through all these hurdles only to tell you you can't fix the problem you want to fix. there's duplicate pages and then lyrics get saved under different songs that they were transcribed on, and it's so nitpicky - it'll tell you something's wrong with the lyrics but it won't highlight what!! It's so counterproductive that it's so hard to fix lyrics because then you get things like this:

like why can't I change the fact that it says that Ray Charles performed all of Billy Joel's songs. they had ONE collaboration. why is Billy's header picture Ray Charles?? Why is Ray Charles featured more prominently on his profile picture??? Why is he with Ray Charles in the first place????

so im listening to alright by parenthetical girls on spotify and noticed the lyrics were off. like way off. not a single correct verse. a whole different song. thought hm thats weird. reports it and looks up these new lyrics. points me to alright by tamela mann. ok thats alright human error they mustve mistaken the artist or something. listens to alright by tamela mann. the lyrics are wrong. what the fuck?

and these are meant to be professionals that review whether or not you can be trusted to submit accurate lyrics

i can only assume that someone did a fuckass job of researching lyrics and only read the ai summary instead of listening to the actual song because how do you mess up this badly

alright parenthetical girls lyrics are supplied by musixmatch and its wrong, and then genius says that those wrong lyrics are from alright tamela mann and its ALSO WRONG

and i still have no clue what lyrics these are from
