Over his nearly two-decade solo career, Justin Timberlake has released 22 singles that have reached Billboard's Pop Airplay chart -- but which is your favorite?
For Timberlake's 40th birthday over the weekend, Billboard ranked every one of his Pop Airplay-charting singles as a lead or co-lead artist, and his debut solo track "Like I Love You" topped our list.

Comes Around" -- plus the Oscar-nominated Trolls track "Can't Stop the Feeling!"
