musicbrainz "data track" not hidden

There is a data track on this audio cd:

http://musicbrainz.org/cdtoc/attach?id=3cjY7CgyYG63EFtCaPs2OOVJcPs-&tracks=13&toc=1+13+266222+150+128337+139600+150448+162372+173591+185067+195373+207484+217995+230206+244557+255448&tport=8000

http://musicbrainz.org/ws/1/release/?type=xml&discid=3cjY7CgyYG63EFtCaPs2OOVJcPs-

Right now rhythmbox 0.13.3 recognizes that the audio cd actually has
only 12 audio tracks and shows them in the list.
But it names them incorrectly, audio track #1 is "[data track]", audio
track #2 is "Rip it up" and so on.

How can this be fixed properly? Should rhythmbox know that artist
id="33cf029c-63b0-41a0-9855-be2a3665fb3b" is a special purpose artist
which should be hidden? Or is that more an implementation detail of
musicbrainz, so that perhaps libmusicbrainz should take care of that?
