New shaker randomly changes songs

We got my daughter a Shaker for Christmas and it worked fine for one day.  Now, about half-way through a song it auto-skips to another song… then gets part-way into that song and skips to another again.  I’ve tried twisting the end (the one that changes songs) a few times in case it was stuck, but it doesn’t fix it.  Has anyone else had this problem?

what fi you format the card and reload the music

     Changed the battery (put in a new one only yesterday - either she used it a lot, the shaker consumes a lot of power, or both) and it seems to be working fine at least for now. 

     If it skips again, will try reformatting.
