I have reached Yuki nirvana
It may be a CM-exclusive track.
On the other hand, episodes used some classical music concerning Kamijou (makes sense, since he's a musician, not composer - he's expected to play classical music most of the time), I remember actually confusing one of these tracks in ep 3 for Yuki's one (while my friend, on the contrary, used to think that Octavia's theme was not composed by Yuki).
speaking of which, Kamijou's playing practice in ep 6 is listed at Puella Wiki's music map as "Asshole playing violin". Everybody loves him...

...when we were sure it was Hanae singing?
It's one of the most expected tracks for me, too.
And I hope it will be longer.

Do you remember when...?

Prologue to Magia? This one was very short, one use and well worked. I'm very curious.

But given the length of the respective scenes they were used in, it makes sense, actually. Personally, I wouldn't mind hearing Credens Justitiam for 5 minutes in a row, with bridges and such - but where to place it in the show? Then again, such tracks get an extended version in the CD, so it's always a pity when they don't.
(at least they changed the arrangement later). But if you're asking about whether she gets her share from Madoka BD sales, it's not far-fetched to assume.

And they did decide to change it rather than tempt fate...
