I think this is a must have tool if you might need to edit music tags.

As basically a Windows guy who purchased my MAC mainly for hi-res music playback, I find myself missing a MAC version of the program dbpoweramp. Between Pure Music and iTunes, I find I have enough music file conversion utility but for getting the last music file details (Doors; Door,The; The Doors; etc.) correct for consistent showing and grouping in iTunes, I need a tag editor. iTunes does a fine job but not with FLAC and some other formats, and the file must be imported into iTunes (first) in order to edit the tags. This program is the best for music tag editing (in the MAC world) I have thus far found. And, it works!
