My 4 year old iPod seems destined for imminent failure. Earlier today it decided it had no music on it at all after I hooked it up to my computer to put some more on, and now as I'm trying to refill it, after restoring it to factory settings the hard drive is making a LOT of noise. Doesn't seem good. If/when it goes, any thoughts on what I should get? Not at all attached to Apple, I just want something that works and has a lot of memory. I've got a 110+ GB music collection, if I can't carry ALL of it with me that's ok but I want say 60 GB minimum. Don't really care about it doing anything else, like videos or wifi or anything. I just want something that plays music.
