It would probably be better to learn from some other group. DragonForce is pretty repetitive, so it gets boring after you listen to the CD once. Most of their sounds remind me of atari games, especially pac-man (Herman Li seems to like making the pac-man sound)... you can see it here if you want to waste time... http://youtube.com/watch?v=e1sOP0TemVM

...but if you like making atari game sounds go and buy that album.
