Anybody know of a decent app. to edit/change artist/album/genre info for more than 1 ID3 tag at once? That is, select a folder or a number of files and change one or more of those attributes of each file?
I use MP3Tag. Read into the functionality, there should be very little grunt work one has to do manually if they know how to use it. If for example your files are organized and named in a certain convention
/Genre/Artist - Album/Track number - Title.mp3
Then you can tell the program files are named that way and it can automatically fill in the relevant ID3 fields.
