I'm looking for a Windows program where I can rename, tag and otherwise manipulate my audio files. Since around 70% of my collection is still MP3 (around 128kbps, *sigh*) I need a tool that can both read/edit ID3 and Ogg tags. Other formats might be useful but not necessary. Mass renaming (ID3/Ogg -> Filename & vice versa) is also a must. And if at all possible it should be either Open Source or Free/Cardware.
Oh, and I want it to be cherry-flavored.

EDIT:
ACK. Maybe I should look before I post. Found similiar topic 4 threads down
