headphones as productivity aid

I'm sure a bazllion people already know this: headphones let you work better. I used to listen to a lot of music when sysadmining at UNSW but that changed when I escaped into the outer world. At the CSIRO I had my own office, which was good for concentration but I found it easy to be distracted. At my current workplace I'm in cubicle land (pretty good cubicle land actually, but nonetheless). I find other people talking very distracting; I'm someone who literally can't think if there's a TV on in the same room; many waiting rooms drive me nuts - I can't even sit and read:-(

I recently got around to buying a decent set of enclosing headphones (SennHeiser HD270s [review @ dansdata]) and am ripping a bunch of CDs to Ogg format (using cdrip [manual] if you care). I'm now in my own little world and actually getting much more done.
