I have to tell you they make it Completely their own. They are BOTH Amazing in their own Rites. Each one has its Great Points. But there is ONE COVER of Radioactive I wish I could get my Hands on to Purchase, and it isn't a cover by someone you would expect to cover that kind of song. The cover I am talking about is the Lindsey Stirling/ Pentatonix Cover. If you haven't heard it you should look it up on YouTube. I think you will see why it is one I HAVE TO HAVE. Hope you like it.
