First, download music software, such as Cool Me, Cool Dog, etc. After finding the song, there is a download button behind the audition. Generally, you will see the download prompt when you move the mouse. After downloading to the local area, you can right-click, select the location to open the file, find the downloaded song, copy it, open your USB flash drive and paste it in.

The second type: web download, such as Baidu music. After opening the song, right-click, select Save As, and then select the save location. The storage location is your USB flash drive.
