Avicii's body is set to be flown back to his home in Sweden later this week.
The superstar DJ and music producer was found dead in Muscat, Oman, where he was on holiday, on Friday afternoon (local time).
The 28-year-old Swede, real name Tim Bergling, retired from performing live in 2016 after suffering acute pancreatitis and having his gall bladder and appendix removed.
Oman police have confirmed there is no criminal suspicion involved in the death.
TMZ has released a photo of Bergling relaxing on a yacht and sipping a drink the day before his death.
While it is unclear whether the drink is alcoholic, Bergling had previously gone sober due to his health issues which were exacerbated by excessive drinking.
Thousands of fans have paid tribute to the DJ, gathering in central Stockholm for a memorial dance party.
The tallest church tower in the Netherlands has played Bergling's most popular tracks from its bells.
Bergling's ex-girlfriend Emily Goldberg shared photos of the couple kissing, with a heartfelt caption telling of her shock.
"Wake me up when it's all over, because I don't want it to be real," she wrote, referencing the lyrics from one of Avicii's hits.
His debut single as Avicii was released in 2007, and he made it big with 'Seek Bromance' in 2010 and the Grammy-nominated 'Levels' in 2011.
During his career Bergling worked with dance star David Guetta, guitarist Carlos Santana, singer Aloe Blacc and rock band Coldplay.
