iTunes Match still seems like partly a mystery on iPhone. So, I am interested in learning more before potentially dropping my music subscription. Questions for early adopters: Do songs automatically begin downloading when streamed? I subscribe to MOG right now partly so that I don't have gigabytes upon gigabytes of music stored on my iPhone, freeing up disk space for apps. iTunes Match would have to be a replacement for that for me to subscribe. Thus it would be useless to me if songs automatically download. Does shuffling work with streaming or do songs have to be downloaded? Can songs be streamed over 3G or are there restrictions? Thanks!
