I have my cd collection of 222 titles copied to my itunes account.Over the years i have customized my choices by deleting songs,combining 3 cd sets into one cd and have changed a lot of cd cover art fit my choices.Im very worried that if I update to itunes 11 my collection will get messed up and will take me ages to set it the way i have it.when you update to itunes 11 does it take your library and copy it over just the way you have it into new itunes 11 or does it change things around?
