DonkeyXote, a lawyer at Microsoft Game Studios has written a blog post explaining why the Guitar Hero II song packs may be priced the way they are. Apparently some people are... shall we say... mildly puzzled about the pricing.
I don't have Guitar Hero II for the Xbox 360 and my Guitar Hero 1 controller is collecting dust. But it's interesting to get a glimpse of the dark, arcane world of music licensing, and the strange systems and organizations that are involved.
