Still sleeping on Alan Walker? Consider this your final wakeup call.
Named one of Billboard Dance's artists to watch earlier this year, the 19-year-old Norwegian phenom has put up eye-popping streaming numbers (more than 1.5 billion on YouTube and 1 billion on Spotify) despite having only released three proper singles -- including 2015 breakthrough hit "Faded," which topped the singles charts in more than 10 countries and peaked at No. 80 on the Hot 100.
Walker's fourth single, "Tired," arrived today (May 19) and appears poised to extend his successful streak. Featuring an anthemic chorus from Irish singer Gavin James, the song showcases Walker's signature melodic production within a more radio-friendly format than his previous outings. It's only a matter of time before America catches up on this kid.
