When I was with Mike Einziger from Incubus, we came up with the chord progression and the melody for' Wake Me Up!' but (with) no real lyrics . None of us (could) sing and we really needed to get that demo down and the only person I knew that lived in LA was Aloe, so I called him and he was free . Lyrics come really easy to him so he wrote them in a couple of hours and we finished the track ." </P> <P> Aloe Blacc, who is not credited on the track, explained to The Huffington Post: "I started writing the lyrics at the top of 2013, travelling back from Switzerland .

I was invited to the studio with Avicii and Mike Einziger from Incubus, and when I got to the studio they had already come up with a chord progression of the song . I came in with the lyrics and I just developed the melody as I heard the chords, and we all thought it was something very strong . We finished the song that night as an acoustic version, then Avicii made the dance mix in a couple of days, and that's what we released to the world, and that was his release ."
