Well I guess that this is the closest a band can get to selling their soul to the devil nowadays. Unfortunately, it seems that it no longer gets you great songs and albums, but rather a few measly bucks in your pocket.
Metal band Slayer has now put its name on a pinball game dubbed the Slayer Pinball Rocks HD, and the game should, as the band suggests, be played loud. The game comes with some mini-games, Slayer voiceovers, etc.
The app is priced at $3, which at the same time might explain why the devil isn't dealing in souls and albums anymore - we're just becoming cheap. Another option is that Jobs pays more than the unholy one, but now we're just being silly.
