How well do you know *NSYNC music videos?

Long before the Directioners and the Beliebers there were the *NSYNC fans. Pop enthusiasts met Justin Timberlake, Lance Bass, Joey Fatone, Chris Kirkpatrick, and JC Chasez for the first time in the mid-’90s, after the group officially formed on Oct. 1, 1995. Taking allegiance to *NSYNC over BSB, fans went on to buy enough CDs to make 1997’s NSYNC, 2000’s No Strings Attached, and 2001’s Celebrity all multiplatinum.

But just how well do you remember the boys and their slick dance moves 20 years later? In celebration of *NSYNC Day, prove your loyalty by identifying the group’s music videos from just one still photo. Test your knowledge, ahead.
