How much?

About 45 minutes most mornings while getting ready for work, and an hour or more each night while reading before bed.

Sounds perfectly normal to me. I do have a dedicated room, and I also listen about 2 hours per week, Saturday mornings. Eyes closed, sitting still, in the sweet spot, just listening. The other posters are listening as background music. For me, my kind of listening is much more enjoyable. YMMV, just my 2c.

Over last 30 years average 5 hours a day, about 80% classical, 20% jazz .

When I am home and conscious the stereo(s) are on .. first thing I do in the morning is turn music on, before getting out of bed. The last thing I do at night before sleep is turn the music off. I probably do about 8 hours of true dedicated listening a week.... I start to get itchy without it!!

tomcarr, you have no idea.  Get off your high horse.
