Well, I got a friend of mine to switch to mac, he got a new 12" PB (which is better and faster than mine, so now i have to be jealous! heh). The reason he finally switched is because his windows laptop completely crashed on him, had to wipe his HD clean and re-install everything. He had all his data and class work backed up, but he did not have his music collection backed up (aside from what he has on CD). So, the question is, can he re-download songs he purchased from iTMS? I got him to go to the advanced menu then 'check for purchases' but it told him everything had been downloaded. Is there a way to re-download music w/o purchasing it a second time? Everything from his old windows machine is gone. Just wondering.
