I highly recommend http://mp3-tag.com/
Highly configurable. Supports FLAC and MP3 (and probably a whole host of
other formats I don't use).
You can load/read/filter thousands of files at a time, make mass changes,
and much more. It also has an export function for many file formats
inlcuding .csv, a format that can be loaded into Excel.
