Is there a program to change the ID3 tags on an MP3 file through right clicking on the file?
There are several. MP3Ext (available for ZDNet, www.hotfiles.com) is an Explorer extension that adds a new page to the Properties menu of .mp3 files. At a glance you can see all the info about the .mp3 file, including the total time, average time, bitrate, layer, frequency, MPEG version, and mode. The program also displays ID3 tag information, which can be edited on the spot. MP3-Info Shell Extension (available from http://tick.informatik.uni-stuttgart.de/~mutschml/MP3ext/MP3ext23b4.zip or through ZDNet) adds a page to the Properties tab when right-clicking. It allows ID3 tag editing, and also other features such as explorer icons based on bitrate, and pop-up info boxes when pointing at files. However, Occasional crashes have been reported when using this program. Another program is MPTagger (available from surf.to/mptagger), which adds tag “guessing” and file renaming functions to the right click menu itself, or can be used as a standalone tagger.
