That article was depressing. I've always considered the move towards the Hollywood cinematic style to mark the death of gaming for me, so reading an article suggesting it should go even further is just ... ugh.
Of course, I'm just a grumpy old school gamer who hates pretty much everything made after 1996. You guys can enjoy your waggle and HD graphics -- I'm going to go play Shinobi.
But to be fair, this is a good suggestion. Modern gaming has done a great job creating an immersive cinematic experience with its storytelling and graphics, so music really should move along with that. Having a "Level 1" track and "Boss" track just doesn't work with the style of today's games.
