Great moments in censorship

Apple's iTunes store carries a collection of Duke Ellington songs called "the Ultimate Collection". Track #92 seems to be called "Pussy Willow".

I say seems to be called because the listing on iTunes is, I kid you not, "P***y Willow".

Now why would they do that? Just think how deeply degraded a culture has to be to reach this level.
What's next?

C**k of the walk.
Lunch b*x
By the pr**king of my thumbs
Mystery writer D**k Francis
Santa c*mes but once a year
The stockings were h*ng out with care.
