Word of Caution:
I downloaded this, but in order to do that you need a Google Play Account that is tied to a payment method. I chose Paypal. Looking at this carefully, I noticed that after Jan 26, 2015 my free Google Play cost $9.99 per month if not canceled.
Maybe I did something wrong on the free download, but I had to Cancel Google in my Paypal Acct. which made the payment inactive.
Just beware about Free Stuff. I did download the zip file ok which is awesome. Lots to songs to blinky.
