according to the generation sequence of MP3 songs file. Therefore, the song which is copied to
U disk first will be played in priority or vice versa. When the user needs to play according to the
specific sequence, they can arrange the copying sequence. If the files copied to U disk can not
be played, please inspect whether the file format is in MP3 format. If not, please switch to MP3
format in computer and then copy to U disk in order to play normally. When copying MP3 file,
you shall copy to the catalogue of U disk. It is suggested to delete all the unnecessary files and
