WATCH: BTS Performs New Smash ‘On’ At Grand Central Station

I gotta be honest, I still haven’t decided if this was really bad ass or really weird to watch. Just because it was empty!

Last night on the Tonight Show, BTS performed their new smash ‘On’ inside Grand Central Station. (Watch the performance below)

And again, it was an awesome performance, especially the dance breakdown, but it was just weird with it being completely empty.
