What I do to make the v2 icons, is to start off by making a genre icon with the original template and then apply various transformations. 
I have saved these as an action set: "v2 icon maker.atn"

I apply the actions in two parts. Play the "v2 icon maker pt1" first. You then have to make sure that the duplicate reflection layer is lined up correctly at the bottom of the original layer. Then play "v2 icon maker pt2". It should make sense when you use it. If you don't want to resize the icon at the end, just go back a few steps after playing "v2 icon maker pt2" by pressing Alt+Ctrl+Z a couple of times.
If you are unfamiliar with using actions in Photoshop have a look here:

I hope that helps
