If you want a song on your iPhone, you pretty much have to use iTunes to get it on there. Either that or buy it directly from the iTunes app on your device.Now, don't get me wrong, iTunes is a good way to buy and organize your music library, but sometimes you just don't want to be locked down like that. So what are the alternatives? You'll probably be surprised, but there's actually more than one way to put music on your iPhone without using iTunes!
