I don't understand why the mp3 music playback speed is slightly slower than the standard PC-based playback. That is the case across all my files which are derived and/or ripped from various sources. There is a noticeable lag in the rhythm that amounts to about 1/60th slower overall playback time.

This feature is not adjustable for music playback. It apparently is an adjustable feature for podcast or audio book playback - but not music. I wish this were not the case. The Fuze is an otherwise very pleasant player to use.
