It goes without saying, even though I'm going to say it, that a measure and a groove are two different things. A transcription is an inanimate guideline. Only a drummer can infuse it with life. Just because a beat is played "accurately" doesn't mean it's played with feel, and a beat without feel is a sad thing to hear. The best drummers operate subconsciously within a numerical framework but forget about the figures and let the rhythm flow. The math is present, but it isn't the fuel that powers the system. The magic comes from something intangible.
