If you buy it off iTunes, you would need to authorize the school computer to play purchased music (assuming it had iTunes installed. If your buying from an mp3 site, then just transfer the mp3 like any other file, and play it like you would if it was on a hard drive.
Reply:any files you can transfer that to your thumb drive of flash drive and transfer it from one computer to another
