Feature: "Editing File Tags...On The Device"

I'm not exactly sure if the new i pod touch...touches on this issue I have haha, I'm pretty serious about how my music is organized, lets say I've uploaded some songs or video's (whether or not it's legal or illegal), but I realize as I'm playing them, the titles/artists/track number or something noticeable is either missing or wrong, I would have to plug the player into the computer and edit the info from the computer, maybe giving the option to have "real time tag editing" on the device would be kinda cool, I know the I pod touch has a touch keyboard function, maybe using something similar to it, I'm just not sure why no company has actually done this yet.
