In the comments to another sentence, it is stated that this sentence is wrong, since menyanyi requires an object, so it should be "saya bernyanyi". Is that correct?
Yes I saw the same comment and wondered too. The comment had mentioned that "me-" verbs need an object, missing here.
Did anyone else listen to the audio at first and think it turned into a goat bleating? Menyanyi-i-i.
I think Duolingo is a mind reader because I was singing when this came up.
