On the U.S. version of the GrimGrimoire Soundtrack,
http://vgmdb.net/album/5152, if you look in the notes section, it says "The price reflects the cost for the whole package (game + soundtrack cd)."
This is incorrect, because the price on this version ($14.99) was the original price of the CD if you ordered from NIS America's old e-commerce website. The original Japanese version was an enclosure that only came with the Japanese game.
Is there a way to break the parent-child relationship these two albums have?
