I have 5.3G of music,too. But I prefer the 8G, for it's extremely sure that Apple will launch a 32G iPod Touch next year, and this device will surely have more juice(I believe the battery test of the iPod Classic and Nano, but a huge screen stuff like the iPod Touch will surely have far less life than 22 hours). So if you don't have much money, and only want to benefit for the "Cool look and use", flash memory,and great screen, choose the 8G like me
