The music downloaded from Kugou is usually an audio file in ".mp3" format. Copy the audio file to a USB flash drive (or other storage device), and then pull it to the classroom computer.
As for whether classroom computers can play music, generally speaking, it is possible. I have worked as a classroom multimedia administrator before. All classroom computers have been installed with various multimedia software, such as Windows Media, Baofengyingyin, QQ Video, Microsoft Office, etc. Among them, Windows Media, Baofengyingyin and QQ Video can play music. .
However, to be more thoughtful, you need to download the Kugou installation package on your computer in advance and put it on a USB flash drive. If the classroom computer cannot play it, then install Kugou in case you need it. .
