I've been searching high and low for this, would love to have the exact music controls we had prior to the 4.4.2 update. I have found an alternative, but it involves using the Samsung Music Player (NOT the stock player we are used to). This music player can be accessed through the Samsung Hub, and you can add a specific shortcut to the music player on your home screen by pressing menu in the Samsung Hub app, and selecting shortcuts. I've tried it, but I don't like it - maybe because it doesn't work as fluid/well? It's worth a try, but I've resorted back to the stock music player.
