I agree, but it existed before this proposal and I didn't want to break
existing markup.

As Karen said:
music by: composer
lyrics by: lyricist

They should be subproperties of creator. I would like to eventually address
author vs creator, but tackling all of CreativeWork is daunting.

Noted on lyricist.

The existing MusicGroup (which is used extensively) is odd. It inherits
from Organization, but the definition states "Can also be a solo musician"
and authors in fact label Paul McCartney as a Music Group.

We could extend the range of byArtist to be MusicGroup or Person to make
the semantics be the same for the properties without breaking the existing
markup. And maybe we can convince authors that Paul McCartney is not a
group. ;-)

Many sources say no. For example, the Lemonheads cover of Mrs. Robinson
sounds very different than Paul Simon's, but according to MusicBrainz, it's
the same composition.

I agree with Karen. Composition forms are not really well defined, which is
why I left it as text.

MusicRecording was the existing name. We needed the same type and I did not
want to break the existing markup.
