I looked through the Laws of LT and didn’t see any mention of a license or restrictions on how people can use the translations that are posted. They don’t allow posting other people’s translations without credit. That’s the closest thing I saw. I checked the FAQ too.

If you do a search for “creative commons” site:lyricstranslate.com, you’ll see some people who add a note that their translation is licensed under Creative Commons. Not everyone does that.

I have to say, LyricsTranslate is the best site I’ve found for song translations. It actually HAS translations, unlike a lot of other sites that show up in the Google results but don’t actually have anything. The quality is usually good, plus it lets you read both versions side by side. I always get happy to find translations there, especially from Romanian to English. Those are pretty rare. So if you’ve posted there already…thank you!
