AnalogX TagMaster

TagMaster lets you edit the ID3 tags in MP3 files, which contains information like the name of the artist, song, album, etc.

It can also rename files using any of the information inside the files including bps and sample rate, making it easier to find the song you're after and it performs any of these operations on single files, or every file in your MP3 directory.
TagMaster works on all versions of Windows, from Window 95 to Windows 7 and everything inbetween including XP, Vista, Win2k, etc.
