i have my .mac account associated with itunes, but the only reason i even have a .mac account is to sync a backup of my settings. I'm finding less and less need for it, especially since it's so overpriced. I went to itunes to change the email address associated with my account but it won't let me. I could create a new account with a new address but then won't i loose all the songs i already bought if i don't use my .mac account? How does that work?
