Have you followed the instructions at http://forum.mybeatbuddy.com/index.php?threads/solution-no-song-error-message.933/

Make sure the SD card is not locked (slider on the side of the card should be moved away from the Lock arrow.

If that doesn’t work, install firmware 1.8.5 to the SD card and try again.

If it still does not work, contact support@singularsound.com
