How many hours weekly do you listen to your system

20 hrs per week, sometimes a bit more, other times a bit less, and periodically an 8-hr session. I have 5-day weekends. I'm lucky.

burning in some tubes and gear
now i'm listening a good 25 hrs a week
Normally it's a lot less

I'd say about 25 hours a week. 4 out of 5 weekdays i fire it up upon walking through the door at 5pm and it's on until 8-9pm a couple hours of TV and its a nite. Sat/Sun as much as possible. About 80% background music while I am doing something else- 20% of the time I am focused solely on the music.

Definitely not enough...

Being retired I get to listen daily.The children are all grown and out of the house.The serious listening is on the 3 days a week my wife works.
On these days it's just me and my music.
