Sometimes you may meet this problem. If you are playing back a MP3 file with ID3 tag version 2.3, please try to skip the music track, the next release of the firmware will resolve this problem. What is ID3 Tag information? ID3 is a metadata container most often used in conjunction with the MP3 audio file format. It allows information such as the title, artist, album, track number, or other information about the file to be stored in the file itself. There are two unrelated versions of ID3: ID3v1 and ID3v2.
