“To make remixing easy, the separate ‘stems’* from the song are available to purchase from iTunes _here_. The ‘stems’ available are bass, voice, guitar, strings/fx and drums. You can mix them in any way you like, either by adding your own beats and instrumentation, or just remixing the original parts.”
