I'm gonna go with Crigger on this, mostly because he's 100 percent right, but partially because I quote him in my tagline.

Everything can and should be counted because over time you'll run into too many things that can't be figured out without knowing how to count it. Case in point: My new friend at work has been playing Rush songs for 25 years. Went over to his house. He can play these songs note for note ... almost. He's been playing the solo portion of YYZ wrong for 25 years. LOL He was playing the notes, just a misplaced 16th note here or there. It sounds (almost) right to the ear the way he played it, and somehow he found his way back to 1. He was stunned when I mapped it out for him.
