Just started tonight and been reading and Regexp are very powerfull stuff. So here is a VERY basic ?.. I kinda of think I know but trying to get a help in the first few days and I should be on a better track as I learn everything..
So the Basic Idea is that MANY of mp3's are not tagged, so to start I'm only concerned with Artist and Titles... My Goal is to take about a 500 untagged files and apply a Filename to Tag Operation however the basic %artist%- %title% is not going to work so I would need to throw in other formats as I have file names such as
Artist - Title
Artist _-_ Title
Artist,\_Title
and a few more which I can work on once I see how it would be the best way to Implement this.

if you need these different patterns then read in all your files but apply a filter next that refects the pattern.
A filter for the first type of files would look like this:
%\_filename% MATCHES .\* - .\*
Select these files and call up "Filename - Tag"
Enter a pattern that looks like this:
%artist% - %title%
The next set of files would be filtered by
%\_filename% MATCHES _-_
The "filename - tag" pattern would look like this
%artist% _-_ %title%
and so on. I hope you can manage now.
