An easy-to use software that combines the flexibility and modularity of user-defined tags and the lightness of a .NET built program. Not only can MetatOGGer handle both MP3 and OGG (both of which all official tags are recognised), but also can it organize, rename, tag from filename, and tag multiple files. These features are built into a scalable two-window solution, which permits to sort songs, to play them (using DirectShow filters) and to preview the modifications before applying them.
