《knock knock》的詞曲是由歌手mxm duk完成,而不是專門為一個人創作的一首歌,該歌曲為男女合唱形式。以下為部分歌曲歌詞:
Knock knock, who's there, who's there, it's me, me, who are you?
(Knock knock) Who are you?
(Knock knock) Who are you?
(I'm) a dreamer, a believer, a believer
(Knock knock) Who are you?
(Knock knock) Who are you?
(I'm) a believer, I'm a believer, I'm a believer
所以,請問的“mxm knock knock歌詞”應該是這個歌曲的一部分,但是我需要更多的信息才能提供完整的歌詞。如果您有任何其他問題或需要更多的幫助,請告訴我!
