Miles said: "This is a fantastic position working with two great multiplatform music brands which are both rich in heritage and constantly innovating. I have thoroughly enjoyed being part of the music marketing team over the last two years and I’m looking forward to continuing to work with the talented teams to build the brands’ success further."
