Avicii, Swedish DJ found dead in Oman

Loved this guys tunes, seen him live at the last T in the Park (Music Festival) i was at in 2013. Sad News..

Avicii Found Dead

Never heard of him.
My first thought was victim of a crime?
But latest info is "no criminal activity suspected"
Articles say he admitted he partied too much, had pancreatitis attack at 21 due to drinking, and burned out on touring a few years back.

Relapse / OD?
Fake 'sripts / opioids (re: Prince)
Legit 'script accidental OD (mix and match)
or Suicide?

I'd hesitate to think suicide, it sounded like he was trying to get back on track.
