I had the pleasure of seeing Rachel Platten live last month and meeting her after her set. She is a sweetheart! The song of hers getting airplay has been 1,000 Ships and the CD version is alright however when you hear the acoustic version it is simply wonderful. You get to enjoy her voice and hear her talent on the piano as well. When an artist can wow you stripped down that is when you know they really have talent. She's got it in spades!
Oh and if you like this you can get the acoustic version on Noisetrade. Her CD, Be Here, has some wonderful songs on it as well.
