When I write stuff it always has a driving feel - i.e. I can do rock and funk fairly well. But I can't write things that swing properly. This either because I simply don't have a swing bone in my body*, or because I'm missing a trick... e.g. I automatically put an emphasis on the first beat of the bar, whereas jazzy rhythms might sound (erm) jazzier if you put that accent elsewhere. * being English and 35 and growing up with the likes of AC/DC, NWOBHM and favouring prog rock.
