Grab it right here,FREE OF CHARGE.

Basically the application contains preview tracks,teaser,intro & gallery.
Nothing’s pretty much new since most of them had been released before.
Get under the cut for more info.

I do see a couple of unseen pictures when the tracks are playing though.
I find the most interesting feature to be the Time & Date calendar which you can enable it at the top right hand corner of the Gallery page.

To get the full features which include the full tracks,MV & extra images,you would need to make an in-app purchase. It cost $5.99USD.
Go check it out for yourselves.
