Any good mass ID3 tagging software for OS X?

I have been looking for decent software similar to Mp3 Tag Studio but for OS X. Primarily I need to be able to tag a song based off of the file name. I've found a piece of software by the name of AudiferousID3 which does batch tagging based on file name(it has all of the fxnality I want) but it's extremely buggy. Also, I've found a piece of software called AutoTagX which is great at tagging files based off of music db's (in fact it's the best I've seen at that - even handles partials) but it doesn't tag off the filename.

So, any Mac users already find this holy grail of tagging software?

I've actually tried that tag editing software before and found that it's missing the key functionality of tagging based on file name. It does let you rename files based on tag info but just not the reverse. It was surprising to me, too, that it was missing that fxnality considering how much fxnality is does offer. Thanks, though.
