Rename from tag

It will rename your file using the data found in the ID3 tags.

The list of signs and what they will be replaced by:
%T - Tag title
%A - Tag artist
%L - Tag album
%Y - Tag year
%C - Tag comment
%G - Tag genre
%N - Tag track number
%F - Current filename (with no extention and path)

Note, that the character case is not important.
Also, there is no need to put the ".MP3 " extension, as Dapyx will put it automaticaly
