I usually listen to it in my office. Once in awhile, I'll have the car to myself on a long drive but 90% of it I listen to on a crappy 15 year old Fisher boombox in my office. I work from home and a quiet house is kind of unnerving if I don't have some music playing. Murf
In the car. I listen to the radio for all of twenty minutes a day. I have a jukebox, but I pretty much have managed to block that out when it's on.
I listen everywhere it seems. All night at work, an hour in the car each day during my commute, about a half hour-hour at the gym everyday, then at home when I'm on the computer.
CDs at the office and in the car. Upstairs on the crappy cd clock radio in my bedroom. On the stereo Saturday/Sunday mornings and usually Friday nights. I have an XM Satellite boombox and a year's subscription that runs out in 2 months. The reception is so bad, I'm not going to renew.
In the car and at my computer. I've started sneaking CDs into work and playing them quietly at my desk though.
From my office on my computer (CDs and streamed on-line radio). I've got these little speakers that plug into Macs for like $80 and they work really well.
At the gym, at home, at work -- Wherever there's a CD player. And once I get my hands on an iPod this X-Mas, everywhere I go.
I used to love to listen to music in my car. Then one of my back speakers blew, not so fun anymore. Then some jackass mother********er broke into my car and ripped my CD player out. not fun at all anymore.
