The Black Rock Shooter OVA is currently being given away for free in the Japanese magazines Megami Magazine and Monthly Animedia, as well as eventually being streamed online. But what if you liked the OVA like Colette did and want to pay the creators for their effort? Is there any incentive to pick up a retail copy?

Well, if you're looking for something to justify a purchase, maybe an exclusive remix of Supercell's song "Black Rock Shooter" (featuring vocals by Vocaloid Hatsune Miku) by Linkin Park's Joe Hahn will tickle your fancy. According to Anime News Network, The remix will be displayed along with a stop-motion film made by Hahn in Hollywood.

Hahn has previously directed the music video for Linkin Park's "Breaking the Habit," working with animator Kazuto Nakazawa of Production I.G. and Eric Calderon of G.D.H. International to create the video. The new DVD extra will be stop-motion, so an anime short is out, but Eric Calderon is involved once more, and supposedly staff who worked on The Nightmare Before Christmas and Coraline are attached to the project. There is no mention of whether the original artist Huke is assisting in this short.

Seeing as Black Rock Shooter is only 50 minutes long and is available for free, would extras like this be enough to interest you in a purchase if the DVD is released outside of Japan? For me, it would have to be priced extremely low before I'd consider it.
