In a recent interview with Billboard, it was not only revealed that the vocalist on Avicii's latest single "The Days" from his forthcoming, 2015-released second album was British star Robbie Williams, but the Swedish superstar also discussed the nature of his touring schedule that led to the artist currently resting in his native Stockholm.

Saying that he's "always had a sense of rush," after having his gall bladder removed and being treated for a burst appendix in March 2014 he cancelled his appearance at Miami's Ultra Music Festival, and though he "took a month off," Avicii says "it wasn't really a month off." Continuing, he says, "I was in the studio 12 hours a day, and then went right back to touring. It's hard to say no in this industry. You want to play everything and be everywhere."

Las Vegas residencies and deals with namely Coca-Cola and Ralph Lauren netted Avicii $24 million in earnings in 2013, but at what cost? After overcoming an addiction to alcohol as well as two major health scares, the idea that the artist's itinerary was set to include a flight from Atlanta to Shanghai (16 hours in the air to a location that is 12 hours ahead) is either par for the course or absolutely frightening (depending on perspective). If this is indicative of the schedule he maintained prior to shutting down for 2014, one can only hope that the producer is relaxing comfortably and healing at this time.

Regarding his client's health, Avicii's manager Ash Pournouri says, "We'll hold everything off until Tim is completely back on track." Continuing, he says, "We're not going to make any presumptions about when that will happen. We're just keeping an eye on him and when he's going to be completely healthy so we don't have to deal with any of this ever again."
