[Smirnoff]

"SOS" is the first posthumous single by Swedish DJ Avicii featuring co-production from Albin Neder and Kristoffer Fogelmark, and vocals from American singer Aloe Blacc. It was released on 10 April 2019 and will be included on his posthumous third studio album Tim, to be released on 6 June 2019.
The song was written and produced by Albin Nedler, Kristoffer Fogelmark, and Avicii. It features an interpolation of "No Scrubs" by TLC, written by Tameka Cottle, Kandi Burruss, and Kevin "She'kspere" Briggs.
The song was released alongside a video featuring comments on the Avicii Memory Board, as well as a behind-the-scenes video that was released two hours before release. It debuted at number one on the singles chart in Sweden on two days of sales.
The song was completed by a team of writers and producers following Avicii's death in April 2018. It was said to be "75–80% done" at the time of his death.
Co-producers Krisfoffer Fogelmark and Albin Nedler confirmed that after Tim's death they received the MIDI file for the song that Tim had produced, and said that all the sounds and notes in the song are from Avicii himself without any additional production. The only additional production done on the track was for Aloe Blacc's vocals.
