I have a Creative Labs Zen Micro, 6 Gigs, which does not hold all of my CDs at once, but 2000 songs will keep me going at the gym for a while. I fed all my CDs to my computer in Windows Media Player which holds them all in about 10 gigs. I can load or unload all or some of the music. If something happens to the Zen, and I am not happy about the reports above, I can easily reload it from the computer. So far, it is working fine and is very small and light. I wear it on my arm at the gym.
