The verb is "loop". I want to loop this song. I want to loop this playlist.

Below are examples under yours of how I would probably say it. They would be more native sounding sentences. Your sentences would be understood as you wrote them though. Please check if I speak right.Thank you! 重复播放同一首歌 repeat one song and again Play that song again. 循环播放列表 repeat the whole playlist Start that playlist again 随机播放 shuffle the playlist Play those songs again How does native speaker usually say?

Are you looking for words on a music player? Then it might be repeat one song and again : 한곡 반복 repeat the whole playlist: 전곡 반복 shuffle the playlist: 랜덤 듣기 or 무작위 재생 if you want complete sentences, they should be: -한곡을 반복합니다. - 전곡을 반복합니다. - 랜덤 듣기를 합니다. or 무작위로 재생합니다.
