Rihanna - Diamonds / M83 - Midnight City Mashup by Peter J Nicholls published on 2012/10/26 23:26:35 +0000 These two songs were next to each other in my iTunes. As I was flicking through, I noticed they were identical keys, and almost identical chord structures. So I altered the tempo of Diamonds and did this very quick Mashup. I may refine it one day. But this was just for LOLs!
