I personally don't get these features. Here in the us most cellular data plans are have monthly caps with overage charges. I can't imagine sucking up data plan minutes for mediocre quality streamed music. I picked up a tiny 16gb usb stick and jammed it full of music and playlists. I'll probably buy another one so i can refill whenever i want and just swap them. I don't have to bother taking my phone out of my pocket because everything else works via bluetooth.
