I could listen to music 24/7. At home we tend to spend a lot of time in the kitchen, preping meals, clean up after meals, folding laundry, helping our daughter out with homework etc. If the TV is off in adjacent family room, then usually there is music playing during these activities. We often have music playing during supper as well. As you can tell this is background music, but our family room is quite large and it sounds pretty good. I don't ever seem to have enough time to sit down in the audio room for dedicated listening.
My wife is currently traveling, last Sunday night my 19 yr old son and his girlfriend dropped by to have supper with my daughter and I . My wife typically does not like loud music, so we used her absence to have a Bob Marley session during dinner. BBQ steak, fine wine and thumping Marley......beautiful!
I work for a large Hi tech company. I installed a Squeeze Center Service on one of lab file servers. Most of the group I work with now stream music from the Squeeze Center over our corporate network to our desktops using softsqueeze as the client and headphones of course.
I also belong to a little Hunt Camp just outside of Algonquin Park. We are blessed with several members who can sing and play guitar. However when they take a break we turn on the tunes. We have DC power provided via batteries/solar panels, so we installed a Cambridge Sound Works DC powered subwoofer and satilite speakers in two corners. I must say it sounds pretty good!
