Shakira sings with Shelton in the single, Medicine. Shakira:
I think I have real folk roots in my previous albums.The acoustic guitars, that type of narrative, songs that have a traditional structure. And I said to Shelton, ‘I want to do that type of song.’ When I wrote the song I didn’t know what direction to go in and I did like eight versions. Dance, pop … but I said no, this is a country song.
