I think this is a big improvement over the last time I looked.

I still feel there's something not quite right about having instruments
on the same level as roles/contributions rather than one level below.
To me it seems that if an actor plays a part then their character has
the same type of relationship to their role as an actor as an instrument
has to a musician's role as an instrumentalist.

Source is a bit weak currently. If it's going to use a fixed vocabularly
it needs at least 'other' in addition to 'unknown'. Also a little ill-defined
in a way; you might have ripped it off a CD or encoded from FLAC,
but where was it before that?  I can see this might be useful for
organising music collections though.

Nice feature to have.
