Hi! I'm looking to buy songs on Itunes and I have multiple accounts to do that, but I'm wondering how many different accounts/ different purchases I can do on my computer? Do I have to use new IP addresses every time? Can I do it on Ipad and Iphone too? If I do have to do different IP addresses, could you kindly send me any reccommendations on how I can do that? Sorry, I'm a newb. Much appreciated! Love this community.
