Your ShoqBox can support WMA files encoded from 5 up to 192kbps with sampling rate from 8.0kHz up to 44.1kHz, however it does not support WMA track, which consists of variable bitrate (VBR). Files in variable bit rate may be skipped by the player. Please contact your music content provider for detail.
The file names of your .MP3 or .WMA files or the folder containing them may comprise non-English or special characters (Unicode). The ShoqBox does not support such characters. Rename your files and try again. Or install Musicmatch in that language from the CD.
