Processed in sequence. That is: if the original order of songs in the USB flash drive is 123, then the order played by the player is also 123. If the original order of songs in the USB flash drive is 321, then the order played by the player will also be 321. Therefore, if you want to change the default playback order of the player, you must first change the order of songs in the USB flash drive. There are generally two ways to change the order of songs in a USB flash drive:

First, when the user directly saves online songs to the USB flash drive, they will be downloaded and saved in the specified order. For example, if the user wants to save 123 songs in the USB flash drive, and the order is 132, then the order of downloading and saving the songs must also be 132. In this way, when the USB flash drive is connected to the player, the playback sequence becomes the specified 132.

The second method is, if the user copies the songs from the computer to the USB flash drive, first open the USB flash drive with the computer, and then right-click the songs in the order specified by the user. Click "Properties" - "Summary" - "Advanced" in the right-click menu. After opening "Advanced", it will enter the editable state. At this time, the user can slightly change the "Value" on the right side of "Music", and finally click Sure.
