I play smile.fm radio while I work. You can stream it on your PC

Because I sometimes go go quilting bees to work on Miracle quilts, I have most of my stuff in a bin on wheels, so if I had a covered porch where it's nice, I certainly would haul my hiney outside to work. Stick my speakers in the windows, and I'm in my own little world.
Unfortunately my deck is an oven in the afternoon, so I hafta work inside.
