Harry Styles World Tour Kick Off Includes Debut of Two New Songs, 'Anna' & 'Medicine'

It's been almost a year since Harry Styles released his self-titled solo debut, and with his world tour kicking off Sunday night (March 11), fans are eager to find out if he has new tunes in store. Turns out he does, and he rolled two of them out during the opening night of his global trek in Basel, Switzerland.

In video caught by fans at the show, Styles -- wearing a black suit with sparkly accents -- strummed an acoustic guitar while singing the catchy chorus to a song fans have dubbed "Anna." In it, he sings, "I don't want you sympathy, but you don't know what you do to me/ Oh, Anna!/ Every time I see your face, there's only so much I can take/ Oh, Anna!"

The song, which appears to be called "Anna" (or "Oh Anna") also included brief snippets of the iconic strummy acoustic guitar hook from George Michaels' "Faith." 

Check out fan-shot videos of the new song below.

Styles also appeared to unleash another fresh track, the intense "Medicine," with the chorus "Can I take my medicine, take my medicine/ Rest it on your fingertips/ Up to your mouth, feeling it out/ Feeling it out." Both "Medicine" and "Anna" are actually tracks that were part of the writing process for Styles' self-titled debut album, as he explained on stage.

The full set list, according to a fan, includes versions of One Direction's "Stockholm Syndrome," "If I Could Fly" and "What Makes You Beautiful," a bit of Ariana Grande's "Just a Little Bit of Your Heart" (which Styles co-wrote), and his now-famous cover of Fleetwood Mac's "The Chain."

Styles' tour continues in Europe through mid-April, then jumps to Australia and Asia and looping to South and Central America and finally hitting the U.S. on June 5, starting with a show at American Airlines Arena in Dallas. See the full list of tour dates here.
