Rolling Stone: You worked on Madonna’s Rebel Heart album a couple of years ago. Have you stayed in touch with her?
Avicii: Not really. I’d love to work with her again, but that was right when I was busiest, and I think she might have been disappointed in me for not being able to put in as much time as she wanted. A lot of things start suffering when you don’t have the energy or time to do things properly. You think you can get away with it, but the quality suffers.

Vamos, que como no estaba full time le dio la patada. Pero no empezó de nuevo, se quedó con lo que tenía hecho.
