Shaker switches off halfway through a song

Just recently my son’s Shaker has started switching off part-way through his favorite song.

I have a 1GB Shaker - SD card is the Sandisk card that came with the device.

No other songs exhibit this behavior (all songs are 128kpbs MP3s).

It’s not a time limit - other songs play for longer.

It’s not the battery.

I tried playing the song directly off the SD card on my PC, and that works fine, so I find it hard to believe that it’s a corrupt SD card…

Have you tried formatting the SD card? after formatting reload the songs see if that works. if not, it must be the SD card.

P.S. Secure a copy of your songs before you format
