"It's the first new music we've heard from Harris since the release of his fourth studio album "Motion" last November, reported Digital Spy.
"1 week until How Deep Is Your Love is released!" Harris posted.
His last "Motion" included a handful of hits including "Under Control", "Summer", "Blame", "Outside" and "Pray to God".
Meanwhile, Harris recently ranked his own hits in a playlist on Apple Music.
The producer named Rihanna collaboration "We Found Love" as his favourite, while Ellie Goulding team-up "Outside" was second and "Feel So Close" was third.
