MP3 & WMA tag editor

[Cache-man]

Can anyone recommend a good freeware (ID3)Tag editor for both MP3's and WMA files.

I have quite a massive collection I'm in the process of properly tagging, so batch processing would be a advantage. Also a windows context menu addition would help.

Thanks in advance guys
