Right now when I ask for English->French translation requests, I get 53% of Korean and Japanese songs showing up due to small bits of English in K-pop and J-pop.
When I broaden the request to English/French/German/Russian -> English/French, I still get 37% of Asian languages :)
It's not a big deal, but maybe an option could be added to filter out some languages, like a third "exclusion" field in the requests selection form?
