So why want Apple allow you to download a song from iTunes on your iphone that you have bought and downloaded before. I bought Gold Digger for my iphone 4 a long time ago. I got the iphone 5 and forgot to put it on it from computer, so I went to iTunes cause I was not near my computer. iTunes says I purchased the song, but want let me download it. Why? The App Store lets you download old purchases again.
