BTW... Of the charts I generated on the previous OSX and transferred to my iPod, the volume deviation occurs at these tempos: 64, 65, 66, 74, 75, 76, 84, 85, 86. I sincerely hope the next iOS update will correct this bug automatically, without having to delete all the old files, re-transfer them and re-sort them into the Playlists. That would be at least 50 songs for me (that I know of) and no telling how many corrupted titles currently archived in the Forum.
