Accessing Songs on Newer Machine.
I have an problem I can't find an answer for. I have purchased tunes from an older itunes account that I no longer use. These songs are on a widows machine. When I upgraded to the iMac, I can see the songs in iTunes, but when I try and play it, I get a prompt to register the song with the computer and it asks for my old itunes password. I can also see the songs on my iPhone, but they will not play. I have forgotten the password, and the email address associated with it is no longer valid and gone. I have most of them on an older iPod Nano. Is therer any easy way to retrive them, or are they lost forever?
