New York City subway passengers spontaneously belt out Backstreet Boys song together

Several passengers in a New York City subway car came together to show the public the meaning of not being lonely in a video clip that has since gone viral on Twitter.

Civil rights attorney Joel Wertheimer was on the train Sunday when a half-naked man walked into his car and blasted the Backstreet Boys' "I Want It That Way" via a portable speaker. Wertheimer captured the moment in a 32-second clip, which shows fellow commuters getting down to the music.

"Had a really tough week and tonight I was on the subway and some guy walks between train cars, shirtless, bumping a speaker. I wasn't in the mood for Showtime particularly. But sometimes people and life surprise you and a little magic happens," Wertheimer explained in his tweet.

Several train passengers are seen in the clip singing along to the boy band's hit track — one seemed so particularly excited that it was as if she wanted to tell the unidentified half-naked man, "Hey DJ, keep playin' this song!"

As of Friday, the clip has received more than 2.5 million views, and fellow Twitter users have, naturally, responded positively.

"Part of what makes NYC special. Easy to hate it but also easy to love it!" one person wrote.

"Seeing complete strangers, of all different races and backgrounds, bonding together in this fashion puts the biggest smile on my face," another wrote.

The video also caught the attention of the boy band, who tweeted in support, "We live for moments like this."
