I heard this track on the radio several times before I knew who it was by, to be honest I thought it was Adele as it is also in her style, but this is a beautiful tune with very powerful lyrics sung by a fantastic new singer/songwriter. There are several covers of this track but this is the original and the best. Can't stop playing it, also check out the official video on her website, fantastic.
I first heard this on Radio 2 and didn't really take to it at first. But it slowly grew on me so I decided to buy it as a download for my Kindle Fire. I listened to some other tracks but wasn't so taken with them, so just went with the single.
