I can see that for software, but not a music file.
Whatever, it makes my head hurt.
<quoted text>But that's not how apple devices work. You can drag and drop mp3 files from your computer onto an android device and the device will recognize them and play them just fine.
Unless things have changed, which I highly doubt, you can't do that with an iphone. You HAVE to use iTunes(Apple's proprietary software) to transfer music files to the device and that software maintains a proprietary database of what music is on the device.
