I don't normally buy CDs because of a song I've heard in a videogame but I made an exception the other day. The final song in Guitar Hero 3 is Through The Fire And The Flames by Dragonforce. It's almost impossible to play but that doesn't matter as you encounter it over the end credits and don't actually have to play along unless you want to.
And it's excellent. Fast, mad, stupid metal. Like Meatloaf on speed. And acid. So I bought the album.
I haven't listened to it yet. I expect it'll be great. Better than the Robbie one, anyway.
