The GodFather is very intuitive and smart; it scans your MP3 folders and it makes suggestions for better names, while still displaying the old name. It is up to you to select the files whose names you want to change.
Apart from changing names, The GodFather has folder management capabilities, too, and after reading the ID3 tag information, it suggests folder structures.
Other features that will save a lot of time and effort and help you organize your music are creating and merging playlists, encoding and decoding with LAME, exporting to file and playing.
Regarding batch renaming, The GodFather provides you with user defined formats using Tag fields, file and folder names or tokens, mpeg bitrate and mode as variables; case conversion; suggesting new names only for potentially wrong files and the undo function.
The batch tag update supports ID3v1 & ID3v2, Ogg Vorbis comments and APEv2 tags. With The GodFather, you can clear specific fields, skip non empty fields, select specific fields to be updated, use the replacement matrix and update tags by copying or auto synchronizing one to the other.
Additionally, The GodFather helps you organize your music by easily managing playlists, restructuring files in your hard disk, finding duplicate files, and importing information from delimited files to rename and update your files.
All in all, The GodFather is a complex application, which will take some time to learn how to use it; on the other hand, once you become familiar with it, you will be amazed at how fast and efficiently you can organize your media library.
The result will be getting rid of weird file names and a better organized music collection.
