If you buy music from amazon.com, and probably other services as well, explicit content has [Explicit] in the album and song title in the file names and ID3 tags. On an mp3 player, sometimes this means that less of the song or album title is visible than otherwise could be because the [Explicit] makes the name too long. I find this annoying and wanted a tool to remove the [Explicit] strings from my library.
Desplicit is a simple command line utility (requires .Net framework) to remove the [Explicit] tags from any files that use ID3 tags, i.e. mp3, m4a, etc. To use the tool, put Desplicit.exe on the desktop or somewhere else easy to get to. Then just drag a folder to the icon, Desplicit will recursively remove [Explicit] from file and folder names, and remove it from the ID3 ‘Album’ and ‘Title’ fields.
I strongly recommend making a backup of the folder you intend to process with Desplicit! Some programs like iTunes will have trouble with the files and folders being renamed, and you’ll have to remove and re-add them anyways.

This sounds great, but, is there a way to go the other way? I want to add [Explicit] to the ID3 tags on some of my MP3 files.
