Opening Song From Itunes In Exs24, can't figure out how to convert file Options

[miaba]

Hi all, it's been some time but a new question has come up. Can anyone tell me how to open a song from itunes in the exs24 sampler? Apparently it needs to be converted into an audio file that can be recognized by the sampler's zone window but i can't seem to figre it out. I hope this is obvious to the more experienced. Thanks!
