Gripe: mp3 Tagging

After examination of players and ID tags my grand tagging plan seems to have hit a stumbling block; ID tags for MP3 files are wildly randomly implemented on different players, it seems, of the three I've tried so far (Winamp, Media Jukebox and Windows Media Player) actually use their own internal database system to implement the ratings system (all of them) use their own numbering system for music type (all of them) and I can't be sure that any of them are actually modifying the tag data in the file at all rather than just storing it for themselves.

BAH!

Anyone know a (Win based) player or program that can manage (and preferably play) music and will modify ID tags in the mp3 files and not just use their own database instead; the ability to add a rating system (maybe in a custom field) would be helpful but I suspect at this rate I'll end up writing my own damn player.

Bah.

Movieeeeee!!

Ok, I doubt it, but anyone want to come and watch One of the best movies of all time, remastered with me? :)
