Most of the time when I use MP3TAG to modify or Edit music files I have to type in the full genre as it doesn't exist .... is there a way I can add to those already available so it makes the job easier and less typing?
Yes, see File > Options > Genres
Thanks @vilson .... I thought it would be that east 
Thanks, but it's really Florian (the developer) who's making it so easy for us!
