Harry, Niall or Zayn: Which 1D Star's Debut Solo Song Fared the Best?

When Harry Styles' first single "Sign of the Times" arrived April 7, he became the third One Direction alum, after Zayn Malik and Niall Horan, to launch his post-boy-band solo career with a debut single -- and fans have taken notice. Here's how each release performed in sales, streams and on the Billboard Hot 100 in its first week.

"This Town" arrived by surprise on a Thursday and debuted at No. 63 on the Hot 100 -- based on just one day of sales and streams -- before speeding to No. 25 in its first full week. (It ultimately peaked at No. 20.)

In week one, "Sign of the Times" hit No. 4 on the Hot 100, logged 23 million airplay impressions and was the top-selling digital song: 142,000 downloads (per Nielsen Music).

Editor's Note: Louis Tomlinson's first post-One Direction song, "Just Hold On," is credited to both Tomlinson and Steve Aoki; this story centers on solo singles.
