After thumbing through my iPOD with frusteration while running, I've noticed I have more "car songs" than "workout" songs. So how do I organize my tunes? I know there is or has to be a way to divide them up into folders or something, but alas I have no idea how to do this. I have the videa iPOD, 30gb. I hate trying to run to something calming when I just want to run. Thanks in advance!
