A tag that would give back a text, showing the title of currently playing music.
Another tag for an artist would be great as well.
Wear 2.0 has its own screen for this. Why clutter yours with redundant info? With gestures turned on I can flick my wrist andkick the media controls up to see the watch face.
I also would like the embedded version of a mediaplayer in a watch face. At best with customizable buttons - but this will stay a dream at the moment.
