I've noticed that a few of the songs in my library will not play completely. They stop part way through, just like they had ended, and move on to the next one. I know the files are complete because if I drag the marker for how much time is left in the song (sorry if there is a technical term for this I don't know) past the quit point, the song will keep playing. But on its own, it won't play past that point. Has anyone else had this problem? What should I do to fix it? Do I need to reimport the songs from the CDs or what? Thanks.
