In response to your question, I'll give you a possibility:
If you use a computer/mobile phone to listen to the song, the reason for the pause is very likely to be the wired, wireless network is not smooth, the cell phone signal is not smooth and cause the song playback pause;
Resolution: Use the cell phone traffic/network signal in the area of the strong audition/download.
You look at the third-party music player (that is, you use the software) to listen to the song song integrity/connectivity is smooth, if the song is not smooth, will also lead to playback frequency pause;
Resolution: look for songs with high connectivity, usually we are searching for a particular song, the list of the first song is the most smooth.
Because the download of songs is too hot, the software charges for the songs, so you can only try to listen to a part of it. Usually you can see a ￥ icon in the download of the songs, which means that it's a money download.
