Whenever you purchase an app from the Apple App Store and you accidentally delete it and lose the backup copy of it on your hard disk, you won’t have any problems downloading another copy from the App Store again. Just hit download, iTunes will recognize you’ve previously paid for it, and start sending you the file. However, this hasn’t been the case with music download from iTunes. Re-downloading a song means paying for it again. According to some reports online, Apple plans to change this system to something more akin to their App Store. Apple has been asking record labels to allow the option of a buying once and downloading an unlimited number of times for music on iTunes. Essentially turning it into the App Store, except this time you download songs instead of apps. If things go according to plan, this change in the iTunes music store policy will be a welcome one. Let’s keep our fingers crossed that the labels approve of it.
