Thought about making this a poll but the categories would be too limiting.
I guess I would categorize my listening by activity and part of the week.
15 minute commute x two ways = 30 minutes x 5
about two albums while at work on closed headphones = 90 minutes x 5
about two mornings/week 30 minutes on my hifi = 30 minutes x 2
about three nights/week 45 minutes on my hifi or good headphones = 45 minutes x 3
Weekday total = 13 hours and 15 minutes or 2 hours and 39 minutes per day
45 minutes of driving each day = 45 minutes x 2
about three hours of at home listening on hifi or good headphones = 180 minutes
Weekend total = 4 hours and 30 minutes or 2 hours and 15 minutes per day
Total for the week
17 hours and 45 minutes or 2 hours and 32 minutes per day
I listen to CDs nearly exclusively (no radio, sat, MP3, vinyl, music channel, etc.).
I'd say I can listen to 24 albums in a week. Some on my at home listening is where I'm doing nothing else but listening to music.
