Death
In 2016, Avicii retired from touring, due to suffering from mental health issues.

On April 20, 2018, Avicii was found dead in Muscat, Oman,  but no cause of death was immediately given. On April 21, Omani police stated that the DJ's death was not suspicious, and on April 26, his family released an open letter stating:

"Our beloved Tim was a seeker, a fragile artistic soul searching for answers to existential questions. An over-achieving perfectionist who travelled and worked hard at a pace that led to extreme stress. When he stopped touring, he wanted to find a balance in life to be able to be happy and to do what he loved most – music. He really struggled with thoughts about Meaning, Life, Happiness. He could now not go on any longer. He wanted to find peace. Tim was not made for the business machine he found himself in; he was a sensitive guy who loved his fans but shunned the spotlight. Tim, you will forever be loved and sadly missed. The person you were and your music will keep your memory alive. We love you, The Family"

On May 1, TMZ revealed that Avicii had killed himself with a wine bottle.

Aftermath
On April 20 (the date of Avicii's suicide), his song sales increased by 6,000 percent while album sales increased by 12,000 percent.
