How to modify a field in a list of files

[Sergio Spina <sergio am spina gmail com>]

I have a long list of files whose "title" field is simply a sequential number, something like this:

>  dir/subdir/fileA.mp3   title: "001"
>  dir/subdir/fileB.mp3   title: "002"
>  dir/subdir/fileC.mp3   title: "003"
>  dir/subdir/fileD.mp3   title: "004"
>  dir/subdir/fileE.mp3   title: "005"

>  ecc.

I want to change the "title" field *adding a word before* the nuber, something like this:

>  dir/subdir/fileA.mp3   title: "Song 001"
>  dir/subdir/fileB.mp3   title: "Song 002"
>  dir/subdir/fileC.mp3   title: "Song 003"
>  dir/subdir/fileD.mp3   title: "Song 004"
>  dir/subdir/fileE.mp3   title: "Song 005"
>  ecc.

How can I do that with EasyTag?

Thanks.
