I've never really listened to them. I, however, dig checking out speed players, it's fun sometimes to ENJOY the athletic approach to music. I would hope that this isn't dismissed by musicians simply because they can't do it, or some other ignorant perspective based on self centered comparative opinion rather than simply sitting back and letting the sounds tickle your brain. If an open minded approach leads a listener to just not enjoy a particular sound or piece of music, so be it, but dismissing music simply because another listener says "it's fast" is ... silly. That's not objective, that' s selective based on a principle that is founded in a philosophy that I can only speculate on at this time... but the speculation based on the information available suggests that I have too many words in this paragraph.
I will type this though: I can't skate all that good, but that doesn't diminish my enjoyment of watching Anaheim crush Ottawa. CRUSHED.
