Yeah, that’s something that I hope will change about iTunes in the future. It also suxors that you can’t move your music from your iPod back into your hard drive without a considerable hassle. There’s third-party shareware that will do it, but it makes no sense to me why iTunes wouldn’t be able to do it. Probably some dumb anti-piracy thing to prevent you from uploading your whole collection to several computers.
But I have a large music collection with more music ripped than downloaded., and it just makes sense for me to keep it backed up anyway, since it’s a lot faster to move over mp3s from a CD-R than to track down and re-rip dozens of CDs. shrug
