Michael, this is such a good point about AC/DC. The parts are "playable" but it takes a high level of nuance to make them sound really good! Spot-on observation. I think a difference between an advanced player and a beginner is that the advanced player can make simple parts sound good. 

The drum teacher Dave Elitch uses this idea in his workshops, too. He makes his students play just a straight 4/4 beat for a couple of minutes in front of everyone, no fills allowed, and the only goal is to sound good. 

That is yet another layer in everyone's development. From easy stuff, to complicated stuff, and then back to the basics.
