Friends,
I presume you’ve purchased songs from Apple via iTunes, so launch the old girl, update to 10.3.1 and go check for the purchases that you’ve lost long ago on old forgotten machines. As long as the iTunes server remembers what you’ve purchased, you can download them again thanks to the giant piles of cash Apple has shoveled into the gaping maw of the music industry. Get them now before it’s too late!
