I had this idea... I thought, upload music to Google Music. Then download whatever music you want to iPhone so you can listen to it without an internet connection, then change it up periodically whenever I want, without connecting my phone to iTunes, being that now the music is the only thing left making have to do that. It backs up automatically through my WiFi connection at home. So far no luck. Does anyone know how I can do this. Is this even possible yet? Even if I have to use something different from Google Music, is there a way to make this basic idea to work? Thanks in advance for any help you guys give.
