here's what i got, Ive never used the Rounded Rectangle feature, now i know its there! lol... there is soo much to do in Photoshop.
I always use to make a rectangle, then use a circle selection tool, copy paste it 4 times, position it in the 4 corners, then go back to rectangle layer and position circle selection tool to delete four corners sharp points, then have to merge all layers to acheive "rounded corner rectangle"
I also added a White translucent glare to the top of the button, made the path with the Pen Tool and selected path with 0 pixel width, ..... yada yada yada... opacity pretty low below 30%
