CD-Tag is an easy to use program for Windows that allows you to manage your MP3 collection. You can encode to various formats, tag your MP3's with ID3v1, ID3v2, and APEv2 tags, rename MP3's and directories to your specification, edit CUE sheets, import album info from CDDB, create M3U playlist files, create and verify SFV/MD5 files, and even create NFO files.
CD-Tag is not just a tag editor, it's a tool to help you organize and standardize your digital audio collection. Your standards are saved in a profile which you use to name and tag your collection. CD-Tag is also a front-end encoder for many popular formats, including MP3, AAC/M4A, FLAC, WMA, Monkey's Audio (APE), MusePack (MPC), Ogg-Vorbis (OGG), WavPack (WV), and True Audio (TTA).
