".... when listening?"
Enjoy... mostly. right off I'll listen for errors or out of whack stuff (if any) going on with the gear itself... Once I've done that brief audible inspection, it's just digging whatever I'm in the mood for...
I'll keep roaming from one genre to another as the mood prevails... the variety and choices being made for the session keep my attention.
I'm only critical when something has been changed, and then only to the point where I've noted the difference (s). Then it's back to plain old enjoying what I'm hearing.
I'm mindful then only of the different quality levels of the recordings.
Recently, I won't even begin a session until late evening 10p +
... and yeah... I'll fall asleep too just before dawn usually.
