Music to create to

I'm trying to determine what music to listen to while working. Or rather which music to listen to which doesn't make me loose my breath and want to curl up in a ball underneath my desk, or want to stand up and shake it for that matter. I need something that is good but not too good, enjoyable but not captivating. I thinks the old geezers might do it for me, like Johnny Cash or Bob Dylan.
If I listen to the really great stuff I just sit there, staring at the computer screen and imagining that I work. Later I wake from my reverie and realize that Im not reading the article, just letting the words shower me, gathering like shredded paper on at my feat. Not much use there I tell ya. I can also recommend to dive into the african continent for some contemporary tunes.
