Being primarily a drummer I can safely say the bottom 60 is pretty laughable. Many I rate highly are among the top 40 but the order is largely arse about tit while there are still too many baffling choices. To put Bonham, Moon, Watts and Starr above jazz greats like Rich and Krupa is taking the piss. I tend to prefer jazz, fusion and funk drummers but there are many non-listed metal/hard rock drummers who could kick the collective arse of most rock players on this list e.g. Simon Phillips, Scott Travis, Brann Dailor, Brian Downey, Mike Portnoy, Vinnie Paul, Charlie Benante and Stephen Perkins,
