Metadata editor for OS X?

[excitingsounds]

Recently I've been using iTunes via a 2TB external (so that I have basically 'unlimited' space), and I've been having my CDs rip directly to a folder on the drive. The metadata from Gracenote often sucks, seeing as how I'm picky about genre organizing and such. Problem is, I don't think the metadata in the iTunes window, when edited, is embedded into the actual file outside of the computer HD, and I'm wondering if anyone knows of a high-quality, reputable, and preferably open source metadata editor to handle this job instead.

 

I would consider using a different ripping software, but I like the way iTunes is convenient, has an error correction option, etc, in other words, it works.

 

Thanks for your help!

"I don't think the metadata in the iTunes window, when edited, is embedded into the actual file"

 

If you are using iTunes to rip to AIFF or Apple Lossless (ALAC) then the metadata is embedded in the files and editing in iTunes does affect the embedded metadata.

 

If WAV then the metadata is not inside the files.

 

I don't know what iTunes does with other formats.
