One sign of winter: the music I keep downloading is either a) depressing folk music or b) tropical. Such as: "No Other Name," and "If I Had Wings," PPM; "Lightning Bar Blues," Arlo Guthrie; "Hawaiian Roller Coaster Ride," and "Hele Mele No Lilo," from Lilo and Stitch. And then there is "Jamaican Farewell," which manages to be both at once.
