It is, necessarily, dependent on reliable ID3 tags. It has a built in tag editor that works pretty well for individual files, but lacks some features for bulk editing. For example, a bunch of my albums had no track numbers in the tags (although the file names included the track number). Juk had no easy way to set the track number for all. After a little searching on alternate tag editors, I've been very happy with EasyTAG -- fortunately also available as Mandrake 10 package.
