This should in theory be possible with current generation technology. I can get this info on my car stereo whether playing across bluetooth or usb, and I could get it on my pebble watch, but frustratingly it's very hard otherwise to find standalone devices that do this. As far as I can make out it's all down to differing bluetooth application profiles and licencing. Again from a customer point of view very frustrating.
