The Columbian singer - whose songs have included bizarre lines such as "I`m starting to feel just a little abused like a coffee machine in an office" in current hit `She Wolf` - admits she struggles to explain the meanings behind the words in her songs. She is quoted by the Daily Telegraph newspaper as saying: "It`s hard to explain my lyrics because sometimes I just write things because they rhyme. I found this metaphor, and I thought it made a lot of sense. A coffee machine in an office has everybody`s fingerprints on it. Sometimes I feel like that." Despite holding strong political views, Shakira deliberately doesn?t air them in her music because she prefers songwriting to be relaxing. She said: "Now that I have the chance to sit down with journalists, I can relax when it comes to music and not use it as another instrument of communication. "When I write, my subconscious somehow finds its way to the surface. It?s not such an intellectual process, it?s more organic."
