I think I like the English version of Got7’s Lullaby just as much, if not a little more than the Korean version; which is bizarre to me because whenever a group releases an English version of any of their songs I try to avoid it as much as possible after the first listen. But it sounds so good. Their grammar is great, the pronunciation is pretty clear and the lyrics actually make sense. Like I can read it and completely understand what they’re saying. They didn’t have to do this but I’m thankful that they did and proud that it came out so well. I’m not sure how the Spanish or Chinese sounds, as I’m not a native speaker to those languages but hopefully someone in the comments who is, can say how it sounded to them.
