I have not upgraded to new itunes fearing it would mess up my collection.I have many multi discs and boxed sets I have combined into single cd listings on itunes.If I were to upgrade would Itunes get confused finding multidiscs already combined by me and break them up or do something else strange making me regret the update.Bottom line is i just want my library to appear as i have it now set up on older version of Itunes. thanks
