I have read the FAQ and searched but seem to be missing something. I am trying to batch edit several files from different recordings. In other words as an example, i have 60 albums that are genre tagged with "rockabilly" i would like to batch edit to "rockabilly; rock; rock & roll". Would someone be willing to point me to link where i can learn about doing this? (preferably step by step).
Note: If i change directory to my entire collection mp3tag loads indefinitely (over 10,000 albums). If this is the only way to make the batch changes i'll let it run over night if necessary. But as a start would love a step by step so i know i'm on the right path.
