At work we are lucky enough to have a relaxed atmosphere and a cool management team that allows us to listen to music of our choosing on a little boom box setup in the corner. Its very nice, and I like having music to keep my spirits high as the day wears on (especially given the gray weather in SF this time of year).
My only complaint about this arrangement is that sometimes people in my office choose to play punk rock at work (ah, the microcosmic democracy at work). Oi oi oi. Its nothing personal to the people I work with (you're all super awesome), its nothing against punk rock (I have been a punk rock fan for some time) its just that I find it very difficult to concentrate when I am having power chords and high pitched harmonization pumped into my ear.
On that note, let me amend the prior sentence about "its nothing against punk rock," because, actually, I do have a problem with pussy punk rock that seems to be de rigeur these days. Anything the f*cks on Laguna Beach would listen to, really (I know this is a gross generalization). To each their own, I guess. I just don't consider much of the noise that is classified as punk rock these days to be in the same vein as, I don't know -- The Misfits or The Ramones. Those were punk bands. Blink 182 and Fall Out Boy, eh, not so much. It is what it is.
Also, you have to consider the source here: a little snot nosed kid running around the Reservation in south-central NM listening to Deicide and Slayer at a very young and impressionable age. So, from the get-go I was a little more inclined to the hard-core edge of the spectrum. Go figure.
