Query: stops during some songs

The 2nd gen unit stops at some point, usually early during some songs and skips to the next song. It does this aall the time on the same songs and I cannot get it to play through. The same song works fine on itunes on the computer, older ipod models, and other mp3 players, just not on this one. tech support was useless after I spent 1 hour on the phone. Other people report the same problem.
