Ok, I need some help. I'm not sure what you can do for me but it's worth a shot..

i'm looking for a song that i heard at kohls last week and it's a girl that has a sweet almost high pitched voice. I'm almost positive she sings " love... you came undone" or something along those lines, my friend thought she sung "love... look what you have done" can anyone help me? it wasn't loud enough in the store to shazamm it on my phone but any help i will love you forever!
