Most brands can adjust the playing order, such as albums and singers. The so-called default order is alphabetical or pinyin. Most MP3 players read ID3 information.

Just like you said, you will play with a few old antiques or inferior products according to the title 0 1 02. Almost all of this still has a problem. If you want an order, you should not only number it, but also copy it one by one with 0 1 02 03 04. . .

If it is for special needs, it must be played in a certain order, or it is suggested that you use a card reading MP3 to play one by one according to the order in the card.
