How do you say this in English (US)? What's different "one more time" and "once again"?

See a translation

@Summerrrrrrr Yes it makes sense

@Summerrrrrrr Your welcome, the difference between "one more time" and "once again" is that when you say "one more time" you imply that whatever is happening you are only doing it once more, but "once again" means that you have already done something, and are currently doing the same thing. It could also imply to do something again, but it doesn't necessarily specify the number of times that it will be done.

@Summerrrrrrr Of course, no problem.
