I would like to change out the music on my 64GB Wifi iPad 2 without using the cable. Besides using iTunes Match, is there a seamless way to do this (I just don't see the point in uploading all that stuff, much of which I don't even like)? I prefer to use the native music app on the iPad for playback, but would consider other apps if they do this and offer an equivalent or a better experience than the native app. My music library is stored on a Windows 7 PC, if that matters. Thanks.
