Stone Cold was originally Demi Lovato on her 2015 album Confident and as a single. It is about trying to be happy about an ex moving on and being with someone else, but still feeling the pain. Kira gives a great rendition of the song, drawing out the conflict of emotions, without being overly dramatic, and the last line is a masterpiece of mixed emotion. This is the performance that Kira gave on the Maltese TV show Arani Issa in early March this year.
You can follow Kira on Facebook, and on her YouTube channel.
