Avicii's first posthumous song, "SOS," is out nearly a year after the death of the Swedish superstar DJ.
The new track is part of the album called "Tim" -- Avicii's real name is Tim Bergling. His collaborators Albin Nedler and Kristoffer Fogelmark released a video explaining how important it was for them to finish their friend's work and the challenges they faced.
The pair said they sought out Blacc for the vocals because Avicii had expressed interest in working with him again after the success of their previous hit.
The accompanying video shows a dark background, and touching messages and memories from some of Avicii's fans.
Lyrics are about some of Avicii's battles
Blacc said he was honored that Avicii wanted him on his album.
"I feel like 'SOS' was a song that was probably ahead of its time for when he wrote it," Blacc said. "He wrote these lyrics obviously about some of his battles and I think it's a really important topic to approach and to share ... to give people the words to be able to say, 'I need help.'"
The song features words that carry more weight in retrospect. They include lyrics about a man who does not get much sleep and relies on love to pull him back from the brink.
"Can you hear me SOS?" Blacc sings. "Help me put my mind to rest."
It also talks about love, drugs and relationships, and the stress that comes with it.
"I get robbed of all my sleep. As my thoughts begin to leave. I'd let go but I don't know how. Yeah I don't know how but I need to now," Blacc sings.
In true Avicii fashion, the hook is catchy and electrifying, and is sure to send crowds to the dance floor despite the song's solemn message.
Album will raise money for mental health
Avicii's family said the rest of the album will be out on June 6, and comprises his remaining work before he died.
"He left behind a collection of nearly finished songs, along with notes, email conversations and text messages about the music," his representatives said.
The DJ and producer died on April 20, 2018, at age 28. His family started a foundation in his honor to raise money for mental health and suicide prevention.
Net proceeds from the album will benefit the Tim Bergling Foundation.
