When I played online yes, I'd usually have music on.
Live I can't bring myself to do it though, I need to be able to hear everything that's going on. And as a dealer a pet peeve was always the tool at the table who had headphones in and was always missing their action...
I often don't listen to music when I am playing poker seriously, I want to concentrate intensely.
