Harry Styles drops first solo single 'Sign of the Times': Listen now

It's finally the moment One Direction fans have all been waiting for: Harry Styles' first solo single has arrived.

As promised in a sneaky teaser commercial during the U.K.'s X Factor on March 25 and the title and cover art reveal on March 31, Styles officially dropped "Sign of the Times" on Friday (April 7). And as expected, it's pretty killer.

Although Styles never gave any hint about how his solo material would sound, he delivered a true spacey rock ballad in "Sign of the Times," something that might fit in more with David Bowie's catalog or perhaps even an epic '90s rock jam like Spacehog's "In the Meantime" than it does with today's top 40. Aside from the familiarity of Styles' voice, this does not sound like a 1D song.

A video for the new single is seemingly on the way soon, as Styles was recently spotted hanging from a helicopter in what was reported as the video shoot for the song. Outside of the video, though, it's unclear whether Styles will be releasing any more new music in the coming weeks/months. But he is slated to perform on Saturday Night Live on April 15, where artists typically perform two songs -- so we may just be seeing another Styles single before we know it.

For now, listen to "Sign of the Times" below:
