Do you listen intently?

On the vinyl systems, yes.

More casually when listening to (ad free) YouTube. 

Music is almost always on in the background while I work.  Once I’m done with work, I often sit for several hours listening intently.

Main system always invested in the music for ambient, I usually use the Sonos Play 5s and go about tasks or on the phone 

Read or sometimes surf ‘n listen. I claim I can do both. Can I?

Probably about 70% intently. Having played brass instrument from the third grade through high school—concert band in HS in the 1950s and early 1960s in a California school district that had a solid music program from the 3rd grade through High Scool—and attended a fair number of Classical concerts both in the USA and Europe, I am very much “into the music.”  I will even turn out the lights after the sun has gone down to just sit and listen without visual distractions. I do this with classical and other music.   Often for hours.
