I agree, and I never said artist should always be editable.
*HOWEVER*, when presenting this in a UI, I've been told that yes,
artist, title, and similar info should be presented as if it were, and
when it's not (which it isn't because GStreamer doesn't allow it to be
editable :)) it should be greyed out.  It's a matter of presentation.

The alternative, to not implement it at all, is just as bad.  At the end
of the day, we have to fix regressions and this was one of them.  I
don't mind at all if people are working on the Big Picture, but it
shouldn't mean I have to wait for it to arrive if parts of it were
already there.

I agree. Which is why I feel uncomfortable with the current tagging
system - I don't think stuff like replaygain tags should be in the core,
and I'm going to look at moving them to the audio support lib without
losing functionality.  But I try to play ball with what is available.
