Hmm, IMO setting shape of rock is job of "clayencoder", not
"modellingclaytag", whatever is the latter supposed to do ;)

No, I want to be able to preserve / add id3 tag "length". Nautilus-media
would know there are two types of tags, and choose better one (probably,
as Thomas says, the "length-streaminfo" as we trust our framework) to be
presented to the user. But Gnome-tag-editor would be still able to get
length-streaminfo _and_ set length-metadata.
