won't play full song

I have one song that the clip won’t play the entire song. It will play on the computer from the clip, but won’t play all of it when disconected from the computer. I have tried deleting from computer and doing a sync to remove it from the clip and that worked. Then reinstalled it to clip, but same thing happens.

I hope I’ve made that clear. The file seems to be complete on the clip, it just won’t play the entire song
