Avicii, 'True' (9/17)
Since becoming one of EDM's major stars with his 2010 Etta James-sampling smash "Levels," Avicii has been playing around 300 shows a year, making a reported $250,000 payday for each. As a result, he had a basically unlimited budget for his debut album, which ranges from rootsy singalongs to pummeling, vocoder-heavy EDM. He sought out some major talent to help: an eclectic crew including Incubus guitarist Mike Einziger; Imagine Dragons; 71-year-old Elvis songwriter Mac Davis; and legendary Chic guitarist Nile Rodgers. Says Avicii, "I wanted to collaborate with songwriters who weren't used to electronic music, which was interesting from the start."
