To me, that seems quite obvious. For my sins, I spent much of my career in IT. This involved much perusal of technical tomes on subjects such as Operating Systems, Production Management, Statistics, Programming In Cobol and more. I can't honestly say that these would have been my choice for bed-time relaxation and getting off to sleep. So yes, my 'learning' stuff (on drums, but, whatever...) has been Joe Morello method books, Max Abrams Drum Rudiments and many more of similar ilk. Slight difference; I listen to Joe Morello for pleasure, too. It's not the same 'listening', though when I'm 'working' on stuff. To me, that seems quite obvious.
