If you're playing music from the cloud, that isn't on your phone, you'll need a good internet connection, either WiFi or cellular. WiFi is better, if it's available where you want to listen, as you will not be using up your monthly data allowance.Thanks... I have music on Amazon and on iCloud and Dropbox. I know I can download them to the phone and play but can I play without downloading on to the phone? If so do I need wifi to do it? Tunebox looks good I will check it out.
thanks
