Do you listen intently?

On my main system, when I'm listening to music, I'm only listening to music. On my smaller computer system, I play music while doing Photoshop work, but I never have music just playing in the background. 

Most of the time I’m sitting in the prime seat and listening closely.  Even if I’m distracted with surfing the web on my laptop, certain passages still catch my attention.  It’s rare that the system is just on for dinner or background music, but sometimes.  

Best guess - 90% focused listening, 10% background

Always unless I'm listening to XM in the car which is rare.

Almost always.  Hence the obsession.

On the vinyl systems, yes.

More casually when listening to (ad free) YouTube.
